TEXT: The authcrs point out the extremely small number Gf publicaticns
on the influence of oxygen on rolyamides. The present work was undertaken
with a view to eluridating the polymer changes produced b- the action of
oxygen all etevated temreratures. The following sucsrances -sere used for
the experiments: Anid (polyhexamethylenp adipamide), granulated and in
fibrcus form; rr-- ~polycaproamide) in the form of granulate, fibera
and films (type fik--4 (PK-4)); granulated and fibrous
(polyeran-~hamide) and Anid r-6r)g (G.-669), a vcpolymer maue -rom ca-pro-

PE:'RIODICAL: Vysokomolekulyarnyye soyedineniya, v. 3, no. 1, 1961, 56-65
TEXT: The authors draw attention to the known fact that polyamide fibers
and films ra7)idly lose their valuable properties under the combined
influence oil air, moisture and light. The Dresent work was undertaken for
the nurnose of studyin.- the effect of UV light unde--- conditions excluding

time: 2 - 140 hr; temperature: 30�20C. After irradiation, the films were
examined by the following methods: Gas-chromatographic analysis of the
volatile decomDosition Droducts in the XT-2111(KhT-214) chromatograph over
MCr-j(MSM) silica gel; viscosity measurement of the Caprone in cresol
solution, and from this, calculation of the molecular weight; end-group
determ.ination by conductometric titration with 11C1 and KOH, respectively;
determination of solubility and ability to swell in cresol; by taking
thermomechanical and strain curves (Polyani instrument); and, in some
cases, by recordin- the UV-, IR and epr (electron paramagnetic resonance)
spectra. These investigations showed that UV irradiation of Caprone films
leads both to synthetic and destructive processes in the molecule.
Irradiation with. light of the near ultraviolet promotes particularly the
latter processes. Decomposition occurs by homolytic photolysi3 of amide
bonds with subsequent cleavage of CO and secondary transformations of the
radicals Droduced. During this process, C-C bonds of the initial molecule
are freauently ruptured with formation of lower hydrocarbons (C2 - C4)'
The occurrence of synthetic and cross-linking reactions (similarly as in
cross-linking of polyethylene under the influence of radiative irradiation)

is mainly due to the cleavage of H atoms and recombination of the macro-
radicals. In the absence of oxygen, UV irradiation, even in high doses,
reduces the mechanical strength of Caprone by less than 30%. The
material does not turn brittle. The author thanks V. V. Voyevodskiy and

TITLE: Studies in the field of polymer synthesis. I. Synthesis of
polyamides on the basis of xylylene diamines
PERIODICAL: Vysokomolekulyarnyye soyedineniya, v. 3, no. 5, 1961, 0699-705
TEXT: Proceeding from the fact that heat-resistant polyamides suitable for
fiber and glass production are formed by symmetric, aliphatic-aromatic di-
amines, a study has been made of the reactions of m-xylylene diamine (A)
and n-xylylene diamine (B) with adipic acid (1), azelaic acid (2), sebacic
acid (3), o-phthalic acid (4), isophthalic acid (5), and terephthalic acid
(6). The synthesis of esters of A with 1, 2, 4, and 5, and of B with 1 and
3 was performed by mixing diamine solutions and acid in 95~o alcohol. B was
synthesized with 2, 4, and 5 at the boiling temperature of the alcoholic
solution. The resulting ester was filtered off. The precipitate was form-
ed not before 24 hr. Since terephthalic acid is hardly soluble in organic
solvents, synthesis A + 6 was effected b., addition of the acid to the

aqu eous diamine solution and by subsequent boiling. Alcohol + benzene
(1 : 1) -were used as solvent for the synthesis of A + 3 because the ester
did not precipitate from 95% alcohol. Table I contains the yields ard
melting points of the esters synthesized. Polymerization occurred either
in the melt or in a cresol solution. The ester B + 6 could not be polymer-
ized this way on account of its insolubility in cresol and its high melting
point. In this case, the polyamide was obtained from an equimolar mixture
of dimethyl terephthalate and p-xylylene diamide. Tables 2 and 3 list data
and properties of the polymers. Polycondensation of xylylene diamines with
o-phthalic acid failed- 501~. of a substance melting at 237-237-50C was iso-
lated. It was identified as diphthalyl xylylene diamine.. The authors
assume a rupture of the reaction chain by formation of a cyclic imide,
owing to the neighboring position of the carboxyl groups. The intrinsic
viscosity of polyamides indicates that their molecular weieht varies between
10,000 and 20,000. The authors thank D. V. Sol:ollskiy and B. V. Suvorov
for the diamine put at their disposal. B. A. Poray-Koshits is mentioned.

TITLE: Initiation of polymerization by means of electric charges
formed on the interface
PERIODICAL: Doklady Akademii nauk SSSR, v. 137, no. 1, 1961, 1171-115
TEXT: After giving a survey of published data concerning interface
polymerization, the authors presume that here the potential drop of the
interface might play an important part, which causes an orientation of the
molecules. Proceeding from the Arrhenius equation for the reaction rate
V: V = A 1 exp(-E,/RT) (1), the following is written down for the reac-
tion on the interface: V = A2 exp(-F,2/RT) (2), where A 2 > Al;
E Ec~ = n23060(y - Tdy/dT). The potential drop thus may
2 ~ '1 -
increase the factor A, and decrease the activation energy. This assump-
tion was checked by initiation of various polymerization processes on the
interface at normal temperature and absence of the usual initiators and

catalysts, and the results were compared with control tests (polymeriza-
tion in a homogeneous system with benzoyl peroxide). The following ex-
periments are described: A 1 - 2 cm thick layer of acrylonitrile(AN) on
glycerin, containing 1 - 2go water, after 10 to 12 hr, gave noticeable
flakes of polymer at 20-22 C, whose molecular weight was found viscosi-
metrically to be equal to 100,000 - 200,000. The air oxygen inhibiting
the radical polymerization of AN produced no effect upon this process. On
the interface AN - H 0, a noticeable polymerization rate was observed only
in CO2 atmosphere. Aethylmethacrylate (MIA) formed a polymer film on the
interface with water or mercury after 30-40 hr. On the interface 1XMA -
paraffin or 1ALIA - glycerin, polymerization occurred after 4-5 hr. This
reaction is accelerated in a CO2 atmosphere. As the admixture of scme
substances increases the potential drop on the interface, the effect of
0.01% CH3COOH, CH2ClCOOH, and HC1 was tested. In the system AN - glycerin
(with 1~'. H20), this addition at 200C led to a polymerization of from
25-30~c' after 15-20 hr. In AN - H20 (1:1) the additional acid in nitrogen

atmosphere after 100 hr gave 1.5~ polymer with a molecular weight of
6,000,000. In the system AN - glycerin - acid, the polymerization rate
was accelerated by water. Experiments, to electrify INA by shaking
(4"-'0-600 vibrations per minute), in the absence of all initiators led to
an increase of viscosity and the forming of 5 - 10';Jo polymer after 3 hr.
The authors thus find their assumption concerning the effect of the
potential drop on the interface to be confirmed, They assume that in this
way also other non-saturated compounds may be polymerized. LlthouEh the
data hitherto available permit no conclusion to be drawn as to the mechan-
4sm of the reaction, a radical mechanism is assumed to exist because of UL,
reaction being inhibited by inhibitors. Mention is made of A. D. Alkin,
V. A. Kargin, V. A. Kabanov, 11. A. Plate, S. S. Medvedev, and N. N.

TITLEi Eff2ct of certain factors on the physicomeahanical
properties of polyvinyl chloride plastics
PERIODICALt Referativnyy zhurnal. Khimiya, no. 5, 1962, 607, abstract
5P30 (Izv. AN KazSSR. Ser. khim., no. 2(18), 1960, 100-107)
TEM In order to improve the corrosion-resisting plastics coatings of
underground pipelines a study has been made of the effect of the main
external factors (contact with petroleum and petroleum products, contact
with mineralized water, the effect of ultraviolet irradiation) oil the
physicochemical properties of polyvinyl chloride plastics (PVC plastics).
It is shown that prolonged contact (up to 20 months) between PVC plastics
and petroleum and gasoline increases the tensile strength of the plastic
but lowers its elasticity as a result of elution of the plasticizers;
analogous changes occur under the effect of ultraviolet light and heat,
In addition to whicht for PVC plastics based on dibutyl phthalate the
percent elongation decreases more sharply, which is due to its high

volatility; the partial elution of plasticizers which occurs when PVC
plastics come in contact with ground water does not lead to deterioration
in the insulating propertios of the plastios. [Abstracterla notet

TEXT: Polyhexamethylene adipamide of molecular weight23,500 was subjected
to heat treatments at 3500C (in N 2 current) and at 380 and 4000C (in an
autoclave and N2 atmosphere) tor several hours each, and the resulting de-
composition products were investigated. *At 3500C, a steric (three-
dimensional) crosslinking of the polymer occurs with cleavage of NE . and
3
CO 20 At 3600C and over, a primary hydrolytic cleavage of the amide bonds
sets in, followed by a separation of CO 2' cyclopentanone, amines, and KH 3*
The presence of CO and low hydrocarbons in the decomposition product
points to an additional homolytic cleavage of the -CO-NH- bonds. The

hydrolysis of the polymer is initiated by the presence of minimum amounts
of moisture in the dried initial product. It is maintained by the forma-

phenolphthalein with terephthalic or isophthalic acid by the method of V. V. ,
Korshak et al., were studied for their stability in a vacuum under ultraviolet
light. Thin fi1M3 were deposited from chloroform solution, dried, exposad for up-
to 120 hrs. to the light of a mercury vapor lamp (6.3 quanta/sec-cm aad analy-

zed by infrared spectroscopy. The gaseous products were identified as carbon mono-
xide and dioxide by gas chromatographic analysis. The coloration of the films

examined by the following methods: Gas-chromatographic analysis of the
volatile decomDosition Droducts in the XT-2111(KhT-214) chromatograph over
MCr-j(MSM) silica gel; viscosity measurement of the Caprone in cresol
solution, and from this, calculation of the molecular weight; end-group
determ.ination by conductometric titration with 11C1 and KOH, respectively;
determination of solubility and ability to swell in cresol; by taking
thermomechanical and strain curves (Polyani instrument); and, in some
cases, by recordin- the UV-, IR and epr (electron paramagnetic resonance)
spectra. These investigations showed that UV irradiation of Caprone films
leads both to synthetic and destructive processes in the molecule.
Irradiation with. light of the near ultraviolet promotes particularly the
latter processes. Decomposition occurs by homolytic photolysi3 of amide
bonds with subsequent cleavage of CO and secondary transformations of the
radicals Droduced. During this process, C-C bonds of the initial molecule
are freauently ruptured with formation of lower hydrocarbons (C2 - C4)'
The occurrence of synthetic and cross-linking reactions (similarly as in

polyamides on the basis of xylylene diamines
PERIODICAL: Vysokomolekulyarnyye soyedineniya, v. 3, no. 5, 1961, 0699-705
TEXT: Proceeding from the fact that heat-resistant polyamides suitable for
fiber and glass production are formed by symmetric, aliphatic-aromatic di-
amines, a study has been made of the reactions of m-xylylene diamine (A)
and n-xylylene diamine (B) with adipic acid (1), azelaic acid (2), sebacic
acid (3), o-phthalic acid (4), isophthalic acid (5), and terephthalic acid
(6). The synthesis of esters of A with 1, 2, 4, and 5, and of B with 1 and
3 was performed by mixing diamine solutions and acid in 95~o alcohol. B was
synthesized with 2, 4, and 5 at the boiling temperature of the alcoholic
solution. The resulting ester was filtered off. The precipitate was form-
ed not before 24 hr. Since terephthalic acid is hardly soluble in organic
solvents, synthesis A + 6 was effected b., addition of the acid to the

aqu eous diamine solution and by subsequent boiling. Alcohol + benzene
(1 : 1) -were used as solvent for the synthesis of A + 3 because the ester
did not precipitate from 95% alcohol. Table I contains the yields ard
melting points of the esters synthesized. Polymerization occurred either
in the melt or in a cresol solution. The ester B + 6 could not be polymer-
ized this way on account of its insolubility in cresol and its high melting
point. In this case, the polyamide was obtained from an equimolar mixture
of dimethyl terephthalate and p-xylylene diamide. Tables 2 and 3 list data
and properties of the polymers. Polycondensation of xylylene diamines with
o-phthalic acid failed- 501~. of a substance melting at 237-237-50C was iso-
lated. It was identified as diphthalyl xylylene diamine.. The authors
assume a rupture of the reaction chain by formation of a cyclic imide,
owing to the neighboring position of the carboxyl groups. The intrinsic
viscosity of polyamides indicates that their molecular weieht varies between
10,000 and 20,000. The authors thank D. V. Sol:ollskiy and B. V. Suvorov
for the diamine put at their disposal. B. A. Poray-Koshits is mentioned.

TITLE: Initiation of polymerization by means of electric charges
formed on the interface
PERIODICAL: Doklady Akademii nauk SSSR, v. 137, no. 1, 1961, 1171-115
TEXT: After giving a survey of published data concerning interface
polymerization, the authors presume that here the potential drop of the
interface might play an important part, which causes an orientation of the
molecules. Proceeding from the Arrhenius equation for the reaction rate
V: V = A 1 exp(-E,/RT) (1), the following is written down for the reac-
tion on the interface: V = A2 exp(-F,2/RT) (2), where A 2 > Al;
E Ec~ = n23060(y - Tdy/dT). The potential drop thus may
2 ~ '1 -
increase the factor A, and decrease the activation energy. This assump-
tion was checked by initiation of various polymerization processes on the
interface at normal temperature and absence of the usual initiators and

catalysts, and the results were compared with control tests (polymeriza-
tion in a homogeneous system with benzoyl peroxide). The following ex-
periments are described: A 1 - 2 cm thick layer of acrylonitrile(AN) on
glycerin, containing 1 - 2go water, after 10 to 12 hr, gave noticeable
flakes of polymer at 20-22 C, whose molecular weight was found viscosi-
metrically to be equal to 100,000 - 200,000. The air oxygen inhibiting
the radical polymerization of AN produced no effect upon this process. On
the interface AN - H 0, a noticeable polymerization rate was observed only
in CO2 atmosphere. Aethylmethacrylate (MIA) formed a polymer film on the
interface with water or mercury after 30-40 hr. On the interface 1XMA -
paraffin or 1ALIA - glycerin, polymerization occurred after 4-5 hr. This
reaction is accelerated in a CO2 atmosphere. As the admixture of scme
substances increases the potential drop on the interface, the effect of
0.01% CH3COOH, CH2ClCOOH, and HC1 was tested. In the system AN - glycerin
(with 1~'. H20), this addition at 200C led to a polymerization of from
25-30~c' after 15-20 hr. In AN - H20 (1:1) the additional acid in nitrogen

atmosphere after 100 hr gave 1.5~ polymer with a molecular weight of
6,000,000. In the system AN - glycerin - acid, the polymerization rate
was accelerated by water. Experiments, to electrify INA by shaking
(4"-'0-600 vibrations per minute), in the absence of all initiators led to
an increase of viscosity and the forming of 5 - 10';Jo polymer after 3 hr.
The authors thus find their assumption concerning the effect of the
potential drop on the interface to be confirmed, They assume that in this
way also other non-saturated compounds may be polymerized. LlthouEh the
data hitherto available permit no conclusion to be drawn as to the mechan-
4sm of the reaction, a radical mechanism is assumed to exist because of UL,
reaction being inhibited by inhibitors. Mention is made of A. D. Alkin,
V. A. Kargin, V. A. Kabanov, 11. A. Plate, S. S. Medvedev, and N. N.

TITLEi Eff2ct of certain factors on the physicomeahanical

PERIODICALt Referativnyy zhurnal. Khimiya, no. 5, 1962, 607, abstract
5P30 (Izv. AN KazSSR. Ser. khim., no. 2(18), 1960, 100-107)
TEM In order to improve the corrosion-resisting plastics coatings of
underground pipelines a study has been made of the effect of the main
external factors (contact with petroleum and petroleum products, contact
with mineralized water, the effect of ultraviolet irradiation) oil the
physicochemical properties of polyvinyl chloride plastics (PVC plastics).
It is shown that prolonged contact (up to 20 months) between PVC plastics
and petroleum and gasoline increases the tensile strength of the plastic
but lowers its elasticity as a result of elution of the plasticizers;
analogous changes occur under the effect of ultraviolet light and heat,
In addition to whicht for PVC plastics based on dibutyl phthalate the
percent elongation decreases more sharply, which is due to its high

TEXT: Polyhexamethylene adipamide of molecular weight23,500 was subjected
to heat treatments at 3500C (in N 2 current) and at 380 and 4000C (in an
autoclave and N2 atmosphere) tor several hours each, and the resulting de-
composition products were investigated. *At 3500C, a steric (three-
dimensional) crosslinking of the polymer occurs with cleavage of NE . and
3
CO 20 At 3600C and over, a primary hydrolytic cleavage of the amide bonds
sets in, followed by a separation of CO 2' cyclopentanone, amines, and KH 3*
The presence of CO and low hydrocarbons in the decomposition product
points to an additional homolytic cleavage of the -CO-NH- bonds. The

hydrolysis of the polymer is initiated by the presence of minimum amounts
of moisture in the dried initial product. It is maintained by the forma-
tion of H20 in the self-condensation of cyclopentanone and its condensa-

TEXT: Polyphenyl-alumino-siloxane was synthesized by reaction of phenyl-j'~
sodium-oxy-dihydroxy-silane with aluminum salfate. The substance showedi
an intramolecular cyclic-network structure, softening point 1600C, By
fractionated precipitation with petroleum ether from benzene solution
fractions of,the polymer were precipitated which had the same composi-
tion; intrinsic viscosity was determined in chlorobenzeneand in benzene,
and the exponent a in the function [TL] - k-Ms' was calculated. At-200G.4,wasl
0.17 in chlorobenzeng,0-345 in benzene. This slight dependence of the
intrinsic viscosity on the molecular weight confirms the dense network
structure of the polymer. There are 8 figures and 5 tables.

ABSTRACT: The reaction of tertiary butyl phenoxyl with diethyl phosphite proceeds
with abstraction of the phosphine hydrogen from monomeric tautomer containing
pentavalent phosphorous. The rate constant in benzene at 20 degrees was found to
be k sub 1 = 1.2 x 10 sup -25 cc/see and the equilibrium constant for the dimeriza-
tion of diethyl phosphite, K = 7.5 x 10 sup -21 an SUP -3. The procedure developed
provides a general kinetic method for determining degree of solvation of the reac-
tion center. Orig. art. has: 3 figures.

Korshak et al., were studied for their stability in a vacuum under ultraviolet
light. Thin fi1M3 were deposited from chloroform solution, dried, exposad for up-
to 120 hrs. to the light of a mercury vapor lamp (6.3 quanta/sec-cm aad analy-
2),
zed by infrared spectroscopy. The gaseous products were identified as carbon mono-
xide and dioxide by gas chromatographic analysis. The coloration of the films
increased and both tensile strength and relative elongation decreased with increa

lene-Isophthalamide were prepared from the diamines, acids, salts and acid chlorie'.es, and
also from dimethylsebacate, by solution; melt; or mixed-phase polymerization, and tested
for intrinsic viscodity in cresol or sulfuric acid solution (deciliter/gram, Ubollodo) and for
thermal stabiliW Maximum yields of 98% poly-m-xylylene-adipamide with a maxinitun
viscosity of 1. 1 were obtained by solution polymerization In m-cresol and subsequerit melt

polymerization at 260-265C. Thermal stability at 237-287C and the typical behavior of a
crystalline polymer were indicated by thermal analysis. Solution polymerization and subse-
quent melt polymerization at 280-290C gave a 98% yield of poly-p-xylylenesebacamide with
B. viscosity of 1. 36 in sulfuric acid; polycondensation yields with dimethylsebacate at 260-
270C were 98% with a viscosity of 1. 17 In sulfuric acid; mixed phase condensation In water-
carbon tetrachloride, gave a yield of 81. 1% and viscosity of 0. 3 in. cresol. Thermalde-
composition of poly-p-xylylene-sebacamide started at 340C, and this polymer wan shown to
be less crystalline than poly-m-xylylene-adipamide. The maximum yield of pply-ni-
xylylene-isophthalamide was 90%, the maximum measured viscosity 0. 17., a6d severe con-
ditions produced crosslinked and insoluble polymers. Decomposition of the amorphous
polyamide started at 350C. OrIg. art. has: 3 figures and 3 tables.

A13STRACT: Polycondensation of m-xylylenediamine with a-phthalic acid at 212-280C in
an inert atmosphere did not yield polyamides of high molecidar weight but linear and cyclic
oligomers; the amount of cyclic polymer increased and that of linear polymer decreased
with an Increase in temperature, and the amount of ammonia liberated was simultaneously
increased whereas that of recovered m-xylylene-diamine was decreased. The polymers,
which were light-yellow to dark brown In color, were fractionated by extraction w1th ethyl
ether, ethyl alcohol, benzene, and acetone, and the benzene-soluble fraction was identified

as m-xylylenediamine diphthdylimide, Formation of ammonia may involve both. the re--
action of terminal aminogroups of polymer. chains and the formation of a secondary amine
from nonreacted m-xylylenediamine. The soluble fractions were shown to contain low-
molecular and cyclic oligomers, and various paths and structures are proposed for the
mechanism of cyclization. Orig. art. has.- 3 tables and 9 chemical formulas.
