(Ref 3). They bring about a certain, rather close distribution
of the forming polymer according to the specific weights (Ref
4). The exchange reactions lead to the fact that in the equi-
librium polycondeneation a state occurs which is denoted as
"polycondeneation equilibrium" (Ref 5). The excess of on* of
the reaction products disturbs this equilibrium and influences
the molecular weight of the formed product (Ref 6, Fig 2). The
present investigation was carried out in order to determine
whether these dependences change if the polycondeneation in
carried out an a non-equilibrium process. As an example of such
a reaction the interaction between dicarboxylic acid chlorides
with diamines may be used (see scheme). If this reaction is
carried out at the boundary between two phases by dissolving
the initial substances'in two liquids which do not mix with
each other (Ref T)9 then it takes place very rapidly.also at
low temperatures i.e. under conditions at which no counter re-
actions occur. The authors investigated the reaction between
hexaaethylene diamine with alkali addition and adipinic acid
chloride. It may be seen from figure 1 that the optimum con-
centration,which leads to high yields in the production of

high-mol*oular products is the 0,15 mol/l solution. Both rea-
gents were solutions of the same concentration. In order to"
solve the problem of the effect of the ratio of the initial
substance on the, molecular weight of the forming polymers a
test series was carried.out in which either the one or the
other initial substance formed an excess. In spite of large
excesses the obtained polyamides had practically no equal mo-
lecular weights (Table I). In the case of an equilibrium poly-
condensation in the reaction of dicarboxylic acids with dia-
mines (Fig 2~ this excess produces strong effects. In this -
pasop the factor which interrupts t~e reaction and the growth,
of the chain is the formation of a polyamide film on the sepa-
ration surface of the phases through which the initial reagents.
may not diffuse. An addition of butyric acid chloride to the
solution of -the initial acid chloride in benzene considerably
reduces the mole6ular weight of the forming polyamide (Figs-3
and 4)- 1 PolYmerp which has groups incapable of reaction, at

TEXT: A summary and discussion of results obtained by the authors
in their previous investigations, published in,1957 and 1958 (-Izv.
AN and DAN SBSR). It was found that for producing linear polymers
from saturated compounds, it is necessary to use peroxides or oth-
er free-radioal forming substances in the molar ratio at least -
11 : I to the saturated compound. The formation of aR-di-iso-pro-
pyl benzene polymer with tert*.-butyl peroxide is discussed in de-
tail. Three different products were obtained: a) A low molecular
weight condeneation.product consisting of dimers and trimers; b)
a high molecular weight product (up to 10,000) linearg soluble in

their experiments with different solvents which were carried out in
order to avoid the formation of insoluble products, but in that
case only compounds of low molecular weight have been obtained. Ex-
periments with the same peroxide yielded linear polymers from the
following hydrocarbons: 2-dichlorobenzene, 2 -xylylendichl-oride,
4,41-di-iso-propyl diphenyl, acetic and trifluoroacetic acid ben-

TEXT: The work described began several years ago with the aim of
finding means of producing terephthalic acid by oxidation with
oxygen from the air. A review of the previous work leada to
the conclusion that the oxidation of p-dialkylbenzenes in the-
gaseous phase is not feasible due to relatively poor thermal
stability of terephthalic acid. A new improved method'of
producing terephthalle acid-1z described, whereby p-xylene:an&
methyltoluate are oxidized simultaneously in the liquid state--,
In this process each of the components oxidizes more-readily than
the compounds taken separately, with 90% yield. The improvement
is explained by the presence in the mixture,-of p-xylene which

helps to maintain the reacting mass liquid and~thus facilitates
the absorption of oxygen. From the point of view of the chemistry
of oxidation, the reaction of a compound difficult to oxidize Is-
facilitate&in the prcsence of another compound which is easy to
oxidize. This is in accordance with the radical-peroxide.
mechanism of Semenov-Bach. TheLsimultaneous oxidation is carried
out in a stainless steel reactor. It was noticed that certain .
metals, such as copper, inhibit the oxidation process. Finally,
a two-stage process for the production of dimethyl-terephthalate.,
was estallished. The first stage is the oxidation of p-.xylene
(98% purity). The beat conditions for this process are as
follows: Catalyst - salts of cobalt (oleate, resinate, mixtures
of acids C7-C9,Cl4-CI6), 0.2%; Temperature: 140 to 1451C;
Pressure% 5 to 10 atm; amount of air: 200 litres/h for
I litre of p-xylene-,, time of oxidation: 4 to 5 h. Under these.
conditions 40 to 45% of p-xylene is oxidized to p-toluic and.
terephthalic acids. The second stage - oxidation of the mixture-
of p-xylene (35%) and methyl p-toluate (65%) - shoul6be carried
out at 140 to 190*C in the presence of cobalt salts. The y1eld:
of acids is between 85 and'90% theoretical., Two methods of

equimolecular quantities of dichlorideg of methyl phosphinic acid with
hydroquinone and nitro-benzene in the temperature range 140-1700 and
with diethyl glycol and dichloro ethane at 40-800 . When studying the
effect of the reaction time an the interaction of the dichloride of
methyl phosphinic acid with dioxy compoundsi the degree of completeness
of the reaction was found to increase especially rapidly within the
first hours of reaction when mainly the initial components react with
one another. The degree of completeness (P) of the reaction was all
calculated from the equation P - X/al where x is the quantity of
hydrogen chloride released until a certain inetantp and a the quantity
of hydrogen chloride theoretically released by a 100% course of reaction.

TEXT: In the present paper, the authors give a report oil the synthesis of
coordination polymers of bis-(8-hydroxyquinolyl)-methane (Oq) with zinc,
nickel, cadmium, cobalt, manganese, and copper, as well as of mixed
coordination polymers of Oq With quinizarin (Q). Oq was synthetized by
reaction of o-hydroxyquinoline with formaldehyde in concentrated sulfuric
acid. Polymerization was carried out with the acetylacetanate of the
metal in nitrogen current, and finally in vacuum at 2200C, or in a
nitrogen current or dimethy1formamide at 120 - 140oct or in dinyl at
2300C. Table 1 gives the analyses and structural formulas, Table 2 the

authors f6und that by mixing a solution of the phosphorus compound in
benzene with a solution of hexamethylenediamine and KOH in water, a poly-
amide film is formed in the interface, which may be extracted as a con-
tinuous twist. In mixing the solutions the polyamide was precipitated as
a white powder, The yield was 72 - 92%. The relative viscosity was de

poor yields of diketones (5%). Proceeding.from, Ref. 2 the authors devalcp
ed a method of direct acetoacetylation of compounds containing several

Ref. 1. By reacting alcoholic solutions of acetates of bivalent metals
(Be, Cu, Ni, Co, Zn, Cd, Mn) with these bis-(P-diketones), or by heating
the bis-(P-diketones) with the acetylacetonates of these metals at a
stoichiometric ratio in the vacuum to 200 - 2500C, the coordination
chain polymers were obtained, whose properties are compiled in Tables
1-6. These are colored powders, partly insoluble, and partly soluble in
few organic solvents. Fig. 1 shows the thermomechanical curve for
(2), Fig. 2 that for (4). These curves are characteristic of crystalline
polymers. The molecular weight of the polymers was betweer. 1000-2000.
The authors found that the following rules govern the behavior of these
polymers: With increasing content of phenyl groups, thermostability
increases while solubility decreases. Solubility and meltability decrease
when the ionic radius of the metal deviates too strongly from the radius
of the chain-forming atoms. Beryllium compounds showed the highest and

TEXT: The authors of the present paper wanted to synthesize mixed poly-
amides by means of non-equillibrium polycondensation in the interface
and to study the influence exerted by the reactivityof the initial
substances on the composition of the polyamides. A mixture of 0.2 mole
solutions of adipyl ohloridejand isophthalyl chloride in benzene was
mixed with a 67-4 mole solution of hexamethylene diamine in aqueous
KOH with 1000 rpm. For comparkson, the same polyamides were produced by
equilibrium polycondeneation,'kby heating the initial substances to

hexame.thyleneisophthalimide is insoluble in formic acid, mixed polymers
with a content of 60%.isophthalio acid were completely soluble in formic
acid (Fig. 1). The formation of a single copolymer was proven by the
infrared spectrum. The products obtained by equilibrium polycondensation
had a higher flowing point than the products synthesized in the interface
(Fig- 3), and had also a higher degree of crystallization. In the reaction
of adipyl chloride and isot'erephthalyl chloride with hexamethylene diamine
in the interface, with the polymer being'extraoted from the interface as
a film, the individual film samples taken during the reaction showed a
perfectly homogeneous structure (Table 2) inspite of different reactivity.
The different reactivity of adipyl chloride, sebacyl chloride, and azelayl
chloride had no influence on the physical properties of the copolymera
with hexamethylene diamine (Table 3) obtained from varying mixtures of
these acid chlorides. The authors thank the laboratory heads of their

TEXT: The authors studied the interfacial polycondensation of adipyl
dichloride and terephthalyl dichloride with hydroqinone. The acid' chlorides
were dissolved in toluene, the hydroquinone in alkaline writer, and the
two solutIons werethoroughly mixed. The reaction with adipyl dichloride
proceeded so fast that no chlorine was detected in the organic phase after
2-3 min. With terephthalyl dichloride, the yield was determined as a func-
tion of the reaction time (Fig. 1). Further, the effect of te erature V~
0 lap
was determined for thiereaction; a maximum was found at 45 C (Fig. 2).
The concentration of components has little effect on the yield. 0-5-1-0
moles/1 is indicated as optimum value. Fig. 3 shows that the yield is
much dependent on the NaOH concentration. The optimum concentration of

The Production of New Types of .Linear-Polymersiby Moans of the
Reaction of Polyrecombination
Doklady Akademii nauk SSSR, ig6o, vol. 132, No. 2, pp. 360-363
TEXT: The authors treated diphenylmethane, some of its derivatives, methyl
ester of phenyl acetic acid, and benzyl benzoate with tertiary butylperoxide
(1.2 and more moles per 1 mole of the initial substances) at 2000, according to
the methods described in Ref. 2. Thus they obtained polymers containing no
noticeable amounts of tridimensional structures. In such cases hitherto it was
only possible to obtain dimers (Refs. 3, 10). Now a linear polymer was obtained
from diphenylmethane which the authors consider to be a polydiphanylmethylene (I)
and which hitherto has not been known (see Scheme). 0It is a yellowish powder
soluble in benzene, with a melting point of 205-220 . Its molecular weight
varies between 10000 and 900000, according to the molar ratio between peroxide
and hydrocarbon. Against all expectations, this polymer shows no inclination

to decompose into free radioals,in--the presence of diphanylpiarylhydrazins. It
is also largely stable towards RNO and chromium mixtures. It is very probable
that the stability of"the polymer Is due to the fact that the firs t product of
the polyrecombinati~6n reaction, namely the dimer tetraphe lethanej is a
completely stable compound (Ref. 5). The structure of polydiphen;rl methylene (I)
was also confirmed by IR-speotra. On the basis of their results, the authors
concluded the followingt tertiary butylperoxide decomposes in such a way that
I mole of peroxide develops only 1 mole of active radicals instead of 2. Hence
the maximum of the molocular,weights 2 moles of peroxide consumption per 1 mole
of hydrocarbon. Half of the liberated radicals which developed originally, are
used for side reactions. From the above-mentioned compounds and others given
in table I the authors in the same way produced linear polymers with a high
molecular weight, soluble in benzene. If durenep ditolylmethane, p,pl-di-iso-
propyl diphenyl, benzylacetate or other compounds are introduced into the
reaction instead of diphanylmethane, large amounts of indissoluble polymers
develop besides linear polymers. Their structure apparently is cross-linked by
methyl groups. Polyreoombination allows the production of linear polymers with
aromatic cycles not onlyin their side-, but also in their main chains. Finally
the authors state that polyreoombination will only produce linear polymers of a

ducing substituents'into the vinyl group the tendency to polymerize
decreases, depending on the structure and nature of the substitu-
ents. Regarding the compounds as substituted ehtylenes it can be
said that 1,1-disubstituted ethylenes are polymerized easier than
the 1,2-disubstituted. The introduction of a phenylic radical cre-
ates steric hindrance to polymerization. B-alkyl silanes polymerize
less than the corresponding C(-compounds, forming low-molecular oils.,

soluble in tricresol. Addition of l14-butanediol to the heated hexame-
thylene diisocyanate yielded no linear polymers. An insoluble, rubber-like )<
substance formed due to cross-linking. For the following reasons, this
method is recommended for industrial application: (1) The reaction rate
of resin formation is higher than in the presence of solvents; (2) the re-
action can easily be regulated by varying the rate of diisocyanate addition;
(3) polymers with the desired molecular weight can be obtained by varying
the rate of diisocyanate addition and the intensity of mixing. There are

TEXT: This r-~!port is a continuation of a study on the synthesis of poly-
urethanes without using solvents (Plast. massy, no. 6, 1961). The effect
of the following factors upon the molecular weight was studied in the
present paper: 1) presence of atmospheric oxygenj 2) ratio of the
components; 3) addition of monofunotional reagents; 4) duration of heating.
The synthesis of polyurethane was conducted by dropwise addition of
hexamethyl diisooyanate to heated 1,4-butanediol. The temperature of the
mass was not allowed to exceed a certain reaction temperature. The melt
was kept at this temperature for a while, and,finally, the viscosity of a
0.5 % solution in tricresol was determined. In calculating the molecular

weight,'the Staudinger constant was set equal to 11-10-4. 1) In the
presence of oxygen, the molecular weight was considerably reduced. In
nitrogen atmosph,ere, the molecular weight was only slightly reduced (from
36,ooo to 33,000) by an increase of the initial temperature of the reaction
from 80 to 1800C. In the presence of air, the molecular weight was
25,000 at 800C and 14,000 at 1000C. An increase of the final reaction
temperature from. 190 to 2300C reduced the molecular weight in nitrogen
atmosphere from 36,000 to 23,000 and in air from 24,000 to 8000. Under
optimum reaction.conditione (initial temperature: 80 to 900C; final
temperature: 200-2100C) the duration of dropwise addition of diisocyanate
in nitrogen atmosphere did not affect the molecular weight. By dropwise
addition of 20 min, a maximum molecular weight of 25,000 was obtained in
the presenoe of air. Slower addition reduced the molecular weight. After
5 hr the molecular weight was unchanged by heating the polymer in N 2 up to
2000C. Heating up to 2100C led to a slight decrease. The presence of air
reduces the molecular weight by 50 ~o within 2 hr at 1900C or within 1 hr
at 2000C. 2) An excess of 1,4-butanediol caused the following changes in

TITLE: Production of linear polyurethanes without solvents. Some
physicomechanical indices of polyurethanes based on hexa-
methylene diisocyanate and a number of glycols
PERIODICAL: Plasticheskiye massy, no. 9, 1961, 16 - 20
TEXT: The authors studied the change in physicomechanical properties of
polyurethanes (PU) obtained on the basis of hexamethylene diisocyanate and
some glycols. The PU were produced by adding the stoichiometric amount of
diisocyanate to the heated diol. The method was developed by the authors
(Plast. Massy, No. 6, ig6i, ibid., No, 7, 1961). The authors determined
melting point, molecular weight (viscosimetrically), and other physico-
mechanical indices. In PU on the basis of diols with different numbers of
C atoms, the maximum melting point lies at 1830C for 1,4-butanediol PU.
Melting points of PU on the basis of glycols with even numbers of C atoms
are slightly higher than with odd numbers of C atoms. Pu on the basis of
ethylene glycol, 1,4-butanediol, 1,6-hexanediol, and 1,10-decanediol are
transparent or white, solid, horny substances which yield cold.-drawing

threads in melting. They are soluble in tricresol or in a phenol-water
mixture (90 : 10). PU based on diethylene glycol and 1,6-methylhexanediol
are transparent colorless elastic substances; they are soluble in tricreso~
in phenol-water mixtures (90 : 10), and also in alcohol-chloroform
mixtures (50 : 50). From the solutions# they form elastic films of high
mechanical strength. Transparent, brittle products are obtainp-d on the
basis of glycols with a secondary hydroxy group such as 1.2-propanediol and
'1,3-butanediol. Pu hardness drops with rising molecular weight of diol.
The side groups and the oxygen atom in diol increase the impact strength.
PU on the basis of diethylene glycol (DE) have low strength and thermal
stability, high water-absorbing capacity, and a large tangent Of the angle
of dielectric losses. The authors found: The presence of a methyl side
group or of ether oxygen in the glycol component reduces the melting
temperature, hardness, thermal stability, and other physicomechanical
indices. Elasticity and solubility in organics increase. PU on the basis
of an ethylene-glycol (EG) - DE mixture are white, elastic, soluble in
cresol, C2H5OH - CHM 3 mixtures (50 1 50), and C 2H5OH - C 2H4Cl I? mixtures.
From melts, PU with high EG content produce strong threads and poorly
elastic films, PU with high DE content, weak threads and solid elastic

films. Melting point, thermal stability, Brinell hardness first drop with
increasing RG content of the mixture, start rising at 35-40% of VEG and reach
a maximum at 100% of EG. The water-abBorbing capacity drops to 0.23% with
100~ of EG. PU on the basis of an EG - 1,4-butanediol (BD) mixture are
white, horny, but less solid, soluble only in cresol and a pheriol-water
mixture (90 % 10). In melting, they yield strong threads and elastic films.
Melting temperatures, thermal stabilities, and impact strengths are lower
in glycol mixtures than in individual diols, the water-absorbing capacity
is slightly higher. PU on the basis of DE - 1.4-BD mixtures are transparent
elastic, and soluble in cresol only. The elasticity of threads and films
from the melts decreases with increasing 1,4-BD content while the strength
increases. PU on the basis of triethylene glycol - 1,4-BD mixtures are more
elastic, and soluble.in C 2H5OH_CHCl 3 and C2R5 OH-C2H4Cl 2' In the same aol-
vents, also PU based on methylhexanediol- 1,4-BD mixtures are soluble.
These PU are white or transparent elastic products. From the melt, they
produce very strong threads and solid films. The impact-strength curve
according to Dinstat of the DE - 1,4-BD mixture passes a minimum with
increasing DE content, and reaches a maximum at about 75% of DE. The
physicomechanical properties of PU are strongly and in a complicated manner

of polyarylates
PERIODICAL: Vysokomolekulyarnyye soyedineniya, v. 3, no. 1, 1961, 72-80
TEXT: The authors point out the scarcity of publications on the chemical
properties of polyarylates. The present study was undertaken with a view
to investigating the possibilities of chemical degradation of polyarylates
of aromatic dicarbo.%3rlio acids, their gasoline and oil resistance,
resistance to dilute and concentrated acids and bases, oxidating agents
and various organic substances. Polyarylates of 2,2-di-(4-hyd-.roxyphenyl)-
propane and terephthalic acid (TD) and isophthalic acid (ID),
respectively, were used for the tests. TD and ID were prepared by

that of 2,2-di-(4-hydroxyphenyl)-propane on TD, the substanoev were added
to varying amounts of -the polymer in ditolyl methane and heated to 2200C
for 3 hr in a stream of 112. The destructive effect of m-cresol on TD and
ID was also tested (0.5% m-cresol solution of polyacrylate was heated to
85-18300). In further tests, TD and ID were heated for 3 hr at 1000C
(or lover, if the boiling point was lower) in ethyl alcohol, iriethylethyl
ketone, dioxane, tetrahydrofuran, n-heptane, benzene, p-xylene,
N,N-dimethyl formamide, methylene chloride, chloroform, carbon tetra-
chloride, tetrachloro ethylene, tetrachloro ethane and chloro benzene.
Gasoline and oil resistance was determined by the method described in
Ref. 18. Results: TD and ID are degraded by 2,2-di-(4-hydroxyphenyl)-
propane, isophthalic acid and m-cresol, but not by isophthalic acid
chloride. Degradation in m-cresol proceeds according to the mechanism of
alcoholysis. The authors calculated the rate constant of the pseudo-

synthesis of grafted and block copolymers. Synthesis of graftecl.and*
block copolymers may be conducted in various alternatives of this method.
Thus, copolymers may be obtained on the basis.of the reactions: (see
below). In-particulart authors obtained grafted copolymers on the basis
of phenol formaldehyde resin and polyarylates from than and isophthalic
or sebacic acids. The grafted copolymer obtained on the basis of 'Plienol'-~
