TITLE: Synthesis and Properties of Polymers With a System of
Cqnjug te Bonds I
PERIODICAL: Khimicheskaya promyshlennost', 1960, No. 6, pp. 6-14
TEXTt The present paper deals with polymers with aromatic
nuclei which
are bound to one another either directly or by such groups or
atoms as to
guarantee a continuity of the conjugate Tir-electron chains
The'accumulation
of benzene nuclei in the macromolecules may lead to the
formation of
linear, linear-annular, angular-annular, ramified, flat
("aromatic
parquet"), or three-dimensional structures. With an increasing
number of
bound aromatic nuclei, the melting point and the
thermostability of
molecules with linear structure increase, while their
solubility falls. An
introduction of methyl groups lowers the melting point, and
improves the
solubility in aromatic hydrocarbons. For the production of
highly heat-
resistant polymers,10those with graphite-like structure are
most interestirg

and polymers with graphite-like structure seems to be mos",
important.
This synthesis can be performed either by conversion of
low-molecular
aromatic compounds, or by intramolecular destructive
cyclization of certain
acyclic high polymers, or by dehydrogenation of polymers
which contain
bound alicyolic groups. A perfluoro polyphenylene obtained
from p-dibromo--
or diiodo tetrafluoro benzene is particularly heat resistant.
Poly-
phenylenes are sparingly soluble in aromatic hydrocarbons,
and show an
anomalous dependence of n/c on o. The high temperature
coefficient of
solubility, the anomalous viscosity, and the dependence of
the intrinsic
viscosity on the displacement velocity, as well as the
unmeltability show
that the polymers consist of relatively short, but strongly
associated,
solid, almost linear macromolecules. An introduction of
methyl groups in
the polyphenylene chain changes the properties of polymers
considerably.
The integral and differential curves for the distribution of
the highest-
molecular fraction of polym;_wthyl phenylene show that the
fraction contains
small amounts of products with molecular weights of up to
300,000. The
author describes the production of linear or poorly ramified
polymeric
aromatic compounds by reaction of Cul+ with benzidine

TITLE; The Pro4uction and Main Properties oArafted Copolymers of
Styrene'land Rubber.
PERIODICALt Kauchuk i Rezina, 1960, No. 6, pp.,,20 - 22.
TEXT: The article presents the results of an investigation on
graft-
ed copolymerization of synthetic rubbers and styrene in aqueous
dispersions
(latexes) and a solution of the polymer in the monomer. The
methods of
conducting grafted copolymerization in heternzenous dispersion
systems of
polymers and monomers in various liquid mediums have been
developed only
slightly. The author has prgliously published an article on the
subject,51

butadiene-acrylonitrile

(SIM-40) rubbers
were taken for the investigation. Table 1 shows the results of
thecompara-
tive characteristics of the rubber and styrene copolymer.(in the
ratio 33:

parties of the produets of the interaction between the styrene
and rubber,
The data show that during the reaction an ifiltiated destruction
of the rub
ber and the formation of branched structures takes place. An
investiga-
tionof the thermomechanical properties showed that the formation
of branch-
ed structures somewhat decreases the vitrification temperature
and the
thermostability according to Martens (75 - 780C instead of 80 -
850C), but
increases the temperature range of the highly elastic state and
the tem-
perature of transference to the viscous-fluid state (Ref, 7). The
styrene
copo2ymers grafted with butadiene-styren3 rubber are not inferior
to the
so-called latex polystyrene as to their dielectric properties and
have a
higher resistance. It is noted that a-comparatively large amount
of rubber
is required in the grafted copolymerization in latexes of
synthetic rubbers,
Apparently in this process the chain transference process takes
place with
a lack of intensity for the following two reasonss 1) incomplete
contact
between the rubber particles covered with the emulsifier and the
monomer,
2) the presence of antioxidant admixtures, disrupting the growing
chains.
When conducting grafted copolymerization in the mass. the
conditions are

more favorable due to a better contact of the ingredients and
because pre-
liminary purification of the rubber from admixtures is
possible. The
authors point out that by developing a method for grafted
copolymerization
of styrene and rubber the amount of elastomer would be reduced
and a more
tensile and durable product could be produced under
atmospheric conditions.
The principle used in Reference I by the author in solving
this problem
is outlined. An investigation of the mechanical properties of
the grafted
copolymers obtained by this method shnwed that even in the
case of a small
amount of rubber added plastics with rather high mechanical
properties
could be produced (Table 3). It becomes apparent that with an
increase in
the rubber latex (under given experimental conditions) the
dispersion and
the stability of-the styrene emulsion increase, which
facilitates the con-
tact between the components and rendets their interaction more
effective.
This, In turn, leads to the formation of the grafted
copolymer. There

TITLE't The Production and Properties of Block-Copolymers Formed
in the
Mastication of Rubber and Polystyrene Mixtures
PERIODICAL: Kauchuk i rezina, 1960, No.12, pp. 1-3
TEXT: The authors have investigated the main physico-mechanical
prop-
erties of materials produced in the mastication of polystyrene and
various
elastomer mixtures. Mention is made of the favorable conditions of
block-
-copolymer-formation, especially in an inert gas medium, during
mastication
of polymer mixtures. It is stated that the mechanism of this
reaction can-
not be ezplained by poly-recombination of the radicals alone,
since in this
case the chain reaetion has the greatest significance, leading to
the for-
mation of black-copolymers and branched macromolecules (Ref.1). The
authors consider that the peroxide macroradicals formed by
interaction with
02 due to the chain nature of the mechano-chemical
block-copolymerization
process can serve as active components taking part in the
formation of the
block-copolymers:

TITLEs Impact-resistant Polyvinyl Chloride
FERIODICkLt Plaoticheakiye massy, 1960, No. 12, pp. 2 - 3
TEM Heat resistance and impact of PVC are comparatively low which
con-
siderably confines its range of applicability in spite of its other
good
Properties. It is possible to increase the impact strength of PVC by
synthesizing vinyl chloride polymers grafted with various rubbers, by
means of a chain transfer reaction. The mechanical properties of
Viniplasts obtained by this method are, however, no better than
those of
Viniplast made of PVC. The present paper investigates the physical
and
thermomechanical properties of Viniplast obtained from compositions
consisting of PVC coplasticized with a polar synthetic rubber(PSR).
Owing
to interaction of functional groups of PVC with the rubber,
interlaced
structures of grafted copolymers are formed. PVC was mixed vith
stabilizers (litharge, calcium stearate) which were hot-rolled along
with
the adequate amount of PSR. Plates were out from thin foils of the

material, and a stack of them was hot-pressed. In the test of
Viniplast
containing 10% PBR of different types, its physical and
mechanical
properties ranged within T following limits: specific impact
strength
from 57.2 to 84.8 kg.cm/cm (8.6 for initial PVC)j maximum
tensile
strength from 3970to 532 kg-CM2 (550 for PVC); vitrification
point
between 76 and 80 C (75 C for PVC). The addition of 10% PSR to
the
Viniplast, thus, increases the specific impact strength up to
the 6 to
10 fold, whereas the tensile strength is somewhat reduced, and
the
vitrification point is maintained. The dependence of the
specific impact
strength, tensile strength and relative elongation on the
rubber content
in Viniplast was investigated (Pigs-1-3). The optimum ratio of
PVC:PSR
for obtaining Viniplast with high apecific impact strength is
90:10
(Fig.1). The introduction of 2.5% rubber increases the impact
strength
of Viniplast to the tbioefold. At a rubber content of 15 - 50%,
Viniplast
samples were not destroyed in the impact test owing to their
high
elasticity. With increasing rubber content, tensile strength and
relative elongation of the material (Fige.2,3) decrease, and
the surface
of Viniplast becomes uneven and rough, beginning from a rubber
addition
of 25 - 30%. The temperature dependence of the specific impact

acetylene
molecules is observed. Substances with structures of the
polyacetylene
type have the same properties as aromatic hydrocarL-onsf namely
that of
taking up.the.energy of ionizing radiation. The laws of phenyl
acetylene
polymerization in.many respects are specific, sometimes e-ven
the opposite
of those of the usual radical polymerization. Stimming up one
may say that
the.polyphenyl.acetylene yield is approximately 8 - 9 molecules
when the
radiation is 100 ev.: In the liquid phase, polymerization'and
initiation
rates are proportional.-The activation energy is.as low as
approximately
700.kcal/mole. A mechanismi was suggested which explains the
unusual
results by-the.specific properties of highly conjugated
products during
the-polymbrization of phenyl acetylene. In these products a
strong de-
localization of unpaired elements takes place, and the
reactivity of
.aimilar~molecules is reduced with an increase in their length.

TEXT: The authors attempted to make graft copolymars from vinyl
chloride
and rubbers. In contrast to the unsuccessful copolymerization
with the aid
of latex reported on in Ref. 2, they used coarsely disperse
rubber emul-
sions. Photogelatins, Sulfanole, or polyvinyl alcohol were used
as emul-
sifiers. Copolymerization vas conducted by two methods: 1)
swelling or
0
dissolving of the rubber in vinyl chloride at4D-70 C, and
subsequent poly-
merization in an autoclave after adding ammonium persulfate as
initiator;
2) rolling of the rubber with ammonium-persulfate powder at
room tempera-
ture, ans subsequent copolymerization with vinyl chloride in an
autoclave
at 60-70 C. Viniplast was made from the reaction products by
adding
calcium stearate, lead monoxide, Neozone D, and transformer
oil, kneading
at 155-170 0C, and pressing. The resulting products showed
worse physical

the concentra-

substance (Table) by comparison with the epr spectrum of
diphenyl-picryl
hydracyl as a standard. All epr spectra showed a signal with
g-factor 0
2.00 which remains unchanged on heating to 300-3500C and
cooling to 77 K,
and-is interpreted as a signal of the conjugate bonds. The
broader epr
signal, which is superposed to this signal-in unheated
samples$ could not
be analyzed because of the superposition, and is interpreted
as a signal
of less active, free radicals with localized free valency.
The signal ap-
pearing additionally in the insoluble fraction with g-factor
2.05, which
disappears on dissolution, is ascribed to low-molecular
particles. The
stability of the epr spectrum in the vide temperature range
indicates the
paramagnetic character of at least part of the polymer. There

12,
pp. 1839 - 1844
TEXT: A new method of obtaining graft copolymers by interaction
between
the polymers is suggested by the authors. This method permits to
modify
halogen-containing polymers with polymers having
nitrogen-containing
heterocycles. A case in point for such a reaction is the
modification of
PVC with methylvinylpyridine rubber under the formation of graft
copoly-
mers which are salts of quaternary polymer bases. Vinyl plastics
obtained
from such polymers have an impact strength ten times as high as
that
prepared solely from polyvinylehloride. Fig.1 illustrates the
temperature
dependence of some thermomachanical properties of some polyvinyl
plastics.
The two-stage formation of trimers is explained. Fig.2
illustrates the
influence of the rubber content on the properties of polyvinyl
plastics.

Fig-3 shows the vitrification temperature of polyvinyl
plastics as a
function of the admixtures. It is demonstrated that the
thermal stability
of polyvinyl plastics is not impaired by a methylvinylpyridine

content up to 25%. The method auggested here may be applied to
vulcanize
various halogen-containing polymers with methylvinylpyri-dine
rubber.

ABSTRACT: The autbors describe now ways of preparing polymeric
materials with
properties required for technical development. one of ihose is the
syntheeis of chelate compounds. Cholates are known.to be resistant
to acids and bases and to agents which react with free metals (Ref
1).
Many 0slates are extremely stable at comparatively high tempera-
turea%14000 and higher). Groups which are able to form chelate
rings
Tlwh--t io' be termed chelating groups. Provided they are suitably
arranged in the molecule, electron donor groups contained in
cholating
groups can form cholato rings in the presence of olootrophilic ions
or atoms. The stability of these oholate rings is much increased if
these donor groups are in conjugation to each other. Examples are
given on p 278. The resistance of those oholate rings to chemical
agents and beat is determined by a number of factors: the structure
and chemical nature of the cholating group, the ring tensiong the
number of rings connected with the corresponding ion, the elcatron
structure of the complezing ion. In most cases, ohelates are highly
