ABSTRACT: Extensive use is now being made of prefabricated and
packaged high- and low-voltage distribution equipment. In
general, Soviet equipment of this kind is larger than foreign
equivalents, which is wasteful in sheet steel, aluminium bus-
bars, etc. Current-carrying parts are usually bare and are
mounted on ceramic or plastic insulators; clearances are con-
sequently large. By insulating these parts, the equipment could
be made smaller. This short article describes appropriate
materials and methods. Yu.F. Voronkov, N.S. Illin and Ya..N.
Kaplunov participated in the development of suitable insulation.
After considerable experimental work, it was decided to investi-
gate a number of polymers including p.t.f.e., poly-amide resin
548, polyvinylbutyral, butadiene-styrol rubber and silicone
rubber. The most suitable material was found to be poly-
ethylene. In the early stages of the work, films of the

material were applied to the conductors, but.this was not very
satisfactory. The best method proved to be hot-spraying with
a special pistol. Air with powdered insulating mterial in sus-
pension is heated bo 0 acetylene flame so that the particles
in molten and plastmaUere to and build up on surfaces with
which they come in contact. The.equipment used to apply
insulation in this way is illustrated diagrammatically.
A polyethylene layer 0.9 mm. thick was maintained in a humidity
chamber for 24 hours and then tested for five minutes at a
voltage of 5 kV/mm without breakdown. The material was also
tested after etposure to heat, light, frost, vibration and water
and iffas generally satisf&ctory. It is concluded that poly-
ethylene insulation of appropriate thickness applied in this
way ,,an be used in distribution equipment for 6 - 10 U. The
work continues. There is 1 figure.

TITLE: Examination of the Use of High-molecular Substances for
the Ieolation of Current Conducting Rails (Issledovaniye
primeneniya vysokomolekulyarnykh veshchestv dlya izolyat-
sii shin tokoprovodov)
PERIODICAL: Izvestiya vysshikh uchebnykh zavedeniy. Khimiya i khimiches-

ABSTRACT: A number of demands is made on the isolation mentioned in
the title, which could not be satisfied for a long time. In
most cases a material perfect in every way proved to be
unsatisfactory with regard to one single characteristic, so
that the rails mentioned in the title could not be isolated.
A uniform point-of-view concerning the electric break-down
of high-molecular compounds is lacking at present. The
authors presume that the electric field strength at whicb a
high-molecular compound breaks down, is mainly determined
by peculiarities of the chemical structure of the macro-
Card 1/3 molecules, further by the structure of the material

for tho Isolation of Current Conduating Haile
based upon a high-moleoular compound, as well as by n num-
ber of external factors which are connected vituh tie
application of the relevant,products. By confronting the
values of a total polarization (electronic, ionic, and
structural), it is possible'to estimate the'suitability of
a material with a certain chemical composition. The struc-
tural polarizationj first established by F. P. Kobeko, is
characteristic of caoutchouc and caoutchouc-like materials.
The purpose of the present paper is an attempt to use high-
molecular materials of such composition and mode of applica-
tion which meet all demands for isolating the rail surface.
Butyl-caoutchouc, butadiene-styreiie-caoutchouc, silicon-
caoutchouc, polyamide-resin 548, polyvinyl-butyral, poly-
tetrafluoro-ethylene (fluoroplast), and polyethylene were
used. A device was set up for testing the resistance to
electric breakdown. All requirements of GOST-664-41 were
satisfied during the tests. only the test voltage was in-
creased to 3,500-5,000 v instead of 2vOOO v. First of all

Examination of the Use.of High-molecular Substances SOV/153-2-2-25/31
for the Isolation of Current Conducting Rails
were discussed. All types of coatings were tested for heat-,
frost-, light-, and ozone-resistanoe, and for vibration.
Tables I and 2 show that the isolation on the basis of
polymer substances, applied in molten state on a heated
metal surface, differs from other isolation methods with
polymers of increased electric strength. The authors
propose a rational method of isolation for the conductor-
rail, that is the application of molten and sprayed poly-
ethylene particles on a heated rail surface. There are 2
tables. I

"Hodifications in the Adrenal Glands in the Course of Intoxi-
cation by Nitrochlorobehzene~" by S. R, Frenkel, Biochemical
Diboratory, Ukraine Central Institute oT-Uh1_o_r_Rygiene, and
Occupational Diseases (director, Docent I. I. Semernin), Fama-
kologiya i Toksikologiya, Vol 20, No 2, Mar/Apr 57, pp 6377-
Experiments were conducted on male and female rats in which intoxi-
cation was induced by single subcutaneous administrations of nitrochloro-
benzene in doses of 500-600 milligrams per kilogram of body weight. The
.effect of the intoxication on the adrenal system was determined by a com-
parative analysis of the content of free adrenalin and adrenalin loosely
bonded with proteins in the systems of normal and intoxicated animals.
The analysis revealed a sharp diminution in the synthesis of adrenalin
by the glands and an increase in the expenditure of the adrenalin after
the intoxication. The complete absence of adrenalin in the glands found
in a number of cases can be regarded as a result of the functional ex-
haustion of the glands after,tbe intoxication by nitroeblorobenzene. (U)

Title Study of linear polymrs with the help of an ultracentrifuge
Periodic&]. : Usp. fiz. nauk 53/2,.161 - 243., June 1954
Abstract : Study of linear polymers by the method of an ultracentrifuge is described.
The polymers were considered with respect to four chaxacteristio para-
meters. The four parameters are as follow, 1. A mean molecular weight;
2. A degree of".the polydispersion determined by the manner of distribu-
tion of molecular weights; 3. A degree of the brancMng; and 4. An
elasticity of the polymeric chains. Kirkwood's, Risaman's Debaye's,
Buache'B, Flory's Fox1a and theories of some other authorities were
.taken into account during the studies and derivatiou of the results,

PERIODICAL: Kolloidnyy Zhurnal, 1958, Vol XX, # 1, pp 67 - 79 (USSR)
ABSTRACT& For investigation of the technical properties of high poly-
mers it is important to know their average molecular weight and
the degree of polydi8persity. These properties are sufficient-
ly known for nitro- and acetyl-cellulose, but for ethyl-cellu-
lose the corresponding values are not available. It is the
purpose of the investigation represented in the article to
supply these values. The technical ethyl-cellulose is not
homogeneous according to chemical composition and degree of
polymerization. For investigation specimens of industrial
ethyl-cellulose were used, which were purified from mineral
admixtures by passing a 1% solution through activated coal.
In fig. 1jthe diffusion factors, the sedimentation constants

are represented. The average molecular weight is calculated
by combining different hydrodynamic parameters. The difference
of the diffusion factors D jm and D is an indication of a con-
siderable polydispersity o the spicimens. The polymers under
investigation are relatively low-molecular. Their molecular
weight dova not surpass 70 : 103- In oxidation the molecular
weight is reduced, i.e. oxidation leads to the destruction of
the polymer chain. In the analysis of the polyd18persity of
the specimens by the method of equivalent Gauss distributions
it is assumed that the sedimentation diagrams form a Gauss
curve. This is true (Fig. 2), but modifications in the low-
and high-molecular branches are present. The hydrodynamic
characteristics are shown in fig. 7 and 8, where the logarithmus
of the sedimentation constant 1g s and the logarithmus of the
charqcteristic viscosity lg Cq 3.aroe dependent on the loga-
rithmus of the molecular weight 1g M. It is shown that

Hydrodynamic Characteristics and Polydispersity of Some 2thylcellulose
Specimens
For both ethyl-cellulose solutions in ethyl-acetate the Staudinger
formula is valid. If the pyran rings are oonsidered as the kinet-
ic elements of the chain, the effective length of an ethyl-cellu-
lose link equals 25 angstrom, which is only of that of nitro-
cellulose. This is an indication of the higher elasticity of the
ethyl-cellulose molecules and corresponds well with its macro-
scopic properties (relative stretching of ethyl-cellulose films
30~, but nitro-cellulose only 5-8~). Fig. 9 shows the dependence
of the logarithmus of diffusion lg D on the logarithmus of the
molecular weight lg M. In table 3 the values of this function
are represented. The dependence of the mechanical properties of
othylc4llulose films on molecular weight is shown in table 4,
where the average molecular weights M, the rupture resistance F
and the relative stretching of the specimens is represented.
It is evident that the mechanical properties deteriorate with
the reduction of the molecular weight.

TITLE: The Thermal Degradation of Polymet'rylmethacrylate (Termiche-
skaya destruktsiya polimetilmetakrilata)
PEMODICALt Kolloidnyy zhurnal, 1958, Vol XX, Nr 4, pp 403-416 (USSR)
ABSTRACT: The production of high-temperature macromolecular compounds
made the study of the thermal degradation of polymers necessary.
In the articlejthe kinetics of degradation of polymethyl-
methacrylate is investigated. Two types of~PMMA were used in
the experiments, one high-molecular with Mo - 3,700,000 and
one low-molecular with MO - 250,000. Figure 2 shows thSt the
degradation reaches 36 1 '~- at temperatures lower than 300 C in
the low-molecular compound, and 5-10 % in the high-molecular
PMMA. The degradation at temperatures higher than 3QOo C is
represented by Figure 3. In the course of 1-1.5 hours it in-
creases 15-30 times. The activation energy during the process
is 53 kcal/molewhich indicates a Tupture of the internal
C - C bonds. Figure 5 shows that nt a degradation of 50 -~jthe
molecular weight is reduced 2C times, The principal cause
Card 1/3 for the reduction of the molecular weight is not the chain

depolymerization. The rupture of C - C bonds leads to the
formation of new chain endings at which depolymerization sets
in. The influence of oxygen on degradation was studied in
P.IN'A powder of 0.1 mm grain size and a sample of massive
PWMA of 5 mm in diameter. Molecular oxygen breaks the kinetic
chains and reacts with free radicals. Tn this renction Iper-
oxides and hydroperoxides are formed which initiate new chains.
Toble 1 shows that in the presence of oxygen an internal
rupture of molecular chains takes place which is, however,
not accompanied by noticeable depolymerization. The influence
of the monomer on the degradation has been studied on a poly-
mer block of 5x5x8 mm which has been inclosed, together wVh
the monomer, in a glass flask. The flask was kept at 120 C
for 1 day. Figure 11 shows that the monomer inhibits de-
pradation by combining with the free radicals without being
polymerized during this 0reaction. liable 2 shows that at
temperatures of 180-280 C/an equilibrium is established
between polymerization and depolymeri7stion. Tn the presence
of oxygen the monomer inhibits the degradation of P,`,!YA by

ABSTRACT: The investigation intended for the explanation of the influen-
ce of the relatively short chains on the brittleness of the a-
bove mentioned polymers showed that a wide distribution of the
molecular weight with a maximum at 250000 is existing and that
therefore the brittleness of -the aryl derivatives of the 14-
-substituted amides of metacr~vlic acid depends on the presence
of strongly aromatic nuclei (benzene) in the side chains. From
the mentioned experimental part can, among othei:rs, be seen that
an oil centriguge according to Svedberg (4ooo rev.99/min) with
an optical system according to Fillpot-Svensson (Ref 5) was
used? that the diffusion coefficient was measured on a LArima
apparatus and that the diffusion constant was calculated ac-
cording to Boltzman-Gralen (Rof 9). The difference of the ob-
Card 1/3 tained results from the theory by Flori-Mandellkern is ex-

TITLE: Investigation of Secondary Reactions in Processes of Radical
Polimerization According to the Formation of "Hybrid Polymers"
PERIODICAL: Zhurnal obahchey khimii, i9599 Vol 29, Nr 8, pp 2750-2760 (USSR)
ABSTIUCT: The authors continued their previous investigation of hybrid
polymers (Ref 1).and in the present paper established directly
the existence of secondary reactions of different types which
include the interaction of macroradioals among one another as
well as the interaction of radicals with the polymer chains. The
evaluation of the hybrid polymer yiela leads to the conclusion
that the reaction, which the authors denote as an inter-chain
exchange or maoromolecular recombination, is less probable than
an increase in the branches of the dione chains instead of an
interaction of the free radicals with double bonds. The behavior
of the newly formed radical after destruction - apart from'
reaction conditions - is determined by the tendency characteris-
tic of the given radical to stabilize due to recombination or by
other means. The more probable, e.g., the recombination typical
Card 1/2 of polystyrene, the greater is the probability of an exchange

*between the chains. Hybrid polymers forming in model systems are
subject to polydispersion to the highost degree with regard to
their amount and compositiong so that it is impossible to
determine exactly the rate constants of the corresponding
secondary reactions. The data of systoms in which the
polimerization of the vinyl compound (styrene) took place in the
presence of the diene polymer (divinyl caoutchouc) confirmed the
data of several authors on the basic possibility to produce
industrial graphted polymers with a "diene backbone" and vinyl
side chains by this simple process (Ref 16). The diagrams given
in the experimental part illustrate the results obtained.

TEXT: The author gives the principles of this method (MWD) which
was developed both by Western and Soviet-bloc workers, including
the author himself, and discusses some typical examples of its ap-
plication. As the polydisperseness ofpolymers is due to the sta-
tistical nature of the polymerization process, governed by the laws
of probability, the study of the polymerization mechanism consists
of determining and subjecting to mathematical analysis the factors
which cause the chain growth and its termination. These affect oth-
er reactions as well, such as the process initiation, the migration
of active centers, etc. The fundamental equation of this method:

A.BSTRACTt The investigation results of the previous paper (Ref 1) were
completed by determining the sedimentation coefficients S, dif-
fusion coefficients D, and characteristic viscosities C-0 on 5
polyisobutylene samples in n-heptane at 200 and at 1 atm. The
values of measurement obtained for these hydrodynamic charac-
teristics are given (Table 1). Three of the samples showed a

M. were taken from reference 1, and indicated together with those
for M and Msr,?719 as well as Mo (Table 3). A simple method is
suggeffed for t5e correlation of the hydrodynamic values of meas-
urement with the direct values 'of measurement for M. and Mw, and
it is pointed out that a similarity to the distribution function,
given by Wesslau (Ref 7) for some of the low-pressure poly-
ethylenes, may be observed. If all conditions remain the same, the
molecular weight of polyisobutylene increases with the duration of
the polymerization reaction. This fact indicates a successive pro-
longation of the linear a'hains. The growing of molecules on cata-
lysts of the Ziegler-Natta. type is assumed to be comparable with
the "growing of a tree". The degree of polymerization depends on
the duration T of the growing process and the rate of growth Y.
The values 'r and v are determined by the properties of the
ternary system monomer - catalyst - solvent. Studies in connection

TEXT: The 9 : 1 methyl methacrylate - methacrylic acid copolymer was
studied by viscosity measurements and by determining sedimentation
constants. The results were evaluated to obtain information on the
conformation of the polymer in various solvent mixtures., The measurement
of the ccncentration dependence of the intrins, v . sity of non-
fractionated polymer solutions (molar weight -:c2-10*19c)oin a mixture of
dichloroethane and dimethyl formamide (DMFA) has shown that the intrinsic
viacosity :-ises gradually with increasing DMFA content, but exhibits a
jump around 90-10VIo DMFA. In pure DMFA, then ' P/c curve takes a course
characteriatic of a slightly ionized Dolyelectrolyte, The polymer is
insoluble -~n pure dichloroethane and swells linearly by a factor of 10..

PERIODICAL3 Vysokomolekulyarnyye soyedineniya, v. 4, no. 2, 1962, 250-255
TEXTs The authors studied the hydrodynamic and mechanical properties of
hybrid polymers on the basis of the selective solubility of one type of
blocks in the corresponding solvent to make a quantitative estimate of
the conformation changes of macromolecules dependent on the solvent, and
to measure the mechanical properties of the resulting films. They in-
vestigated 495 styrene - isoprene bulk copolymer (BCSI) made with butyl
lithium and consisting of four polystyrene (PS) and five polyisoprene
(PI) blocks. The molecular weight determined in methyl ethyl ketone was
M - 77,000, that of PSs M,:z~10,000, that of PIj M V,7500. Solvents
used weres benzene, toluene, heptane, octane, and methyl ethyl ketone.

sion coefficients were determined at O~05% con(.-entration by a Tsvetkov
diffusometer. The sedimentation coefficients were determined by a
Svedberg ultracentrifuge. The molecular weight was calculated according
to Svedbergs M - (S RT)/LD(1-:~Q)l (2). and Flory and Mandellkern,

tion of sta sti aynodes of macromolecules, the linear dimensions being
proportional to M 1/2+6 (t - small parameter). The coincidence of
different mean weights in different solvents indicates weak polydispers.-ty.
The absence of a relation between MS rAnd MSD and the naean hydrodynamic
weights Me, and MD1, demonstrates the unsuitability of the model of

solution. Therefore, they form small pearls threaled on the polvisoprene
string. In methyl ethyl ketone, it is vice versa. Flory's theory does
not apply to this case. There is no relationship between "viscous" and

TITLE: Hydrodynamic proportion of poly-O-viny'i naphthalens macro-
molecules in benzene

TEXT: Diffusion constants, sedimentation coefficients and intrinsic
viscosity of 10 fractions of poly-6-yinyl naphthalene (P-(~-VN) in benzene
were studied. The Mark - Kuhn - Bouwink relations in this solvent were
4.M-0 57 for the diffusion coefficientt
found to have the form D - 3-5-10- S';
-5 0-71
and 6.6-io *11S,D for the intrinsic viscosity. The molecular weight

P-(;-VN, which is determined by viscosity and diffusion, is completely normal,
and confirms the universal character of the empirical constant

slightly-.- exceeds the corresponding values for most of the linear polymers,
showed (e. g. in comparison with polystyrene) that the substitution of the
benzene ring by naphthalene increases the thermodynamic hardness of the
macromolecule. It was found that the dependence of the diffusion coegficient
D on the concentration of one of the P-.)*-VN fractions with M a 3-5*10 is
only slight'in CCL4 and more marked in benzene. This confirms that the
dependence on the concentration is mainly determined by the thermodynamic
interaction between polymer and solvent. (Ref. 13, V. N. Tsvetkov, S. 1.
