TITLE: The Ia spectra of graft copolymers of i;o1&*tyrene ana
porchlorovinyl with acrylonitrile, obtained under x-radiation
PERIODICAL:- Vysokomolekulyarnyye soyedineniya, V. 4, no. 6, 19629 907-912
TEXT; The IR spectra -were investigated for the graft copolymers of poly-
styrene with acrylonitrile (POA) and perchlorovinyl with acrylonitrile
(PCA), obtained by t-radiation. The graft copolymers were prepared
according to the authors (Yezhdunarodnyy simpozium po makromolekulyarnoy
khimii (International Symposium on Macromolecular Chemistry), Koskva, iun'
1960 g. sektsiya III, p. 270). The radiation dose was 1 - 10,000,000
roentgen. For spectral analysis KBr compacts were produced. A double-
beam IR spectrophotometer type O.KC-14 (IKS-14) was used with NaCl prism
for 2.5 - 15 Homopolymerization of acrylonitrile and graft copolymeriza-
tion with pX;styrene takes place during graft copolymerization. Since
the spectrum of the graft copolymer differed from that of the initial

during irradiation. The graft copolymer of polystytene with acrylonitrile
corresponded to oscillations at; 2.86 - 2.94),A. to hydroden bond (f, ..... H);

chlorovinyl and acrylonitril, there corresponded the bandas 2.91P to NH

ABSTRACT: A study of the thermomechanical properties of grafted copolymers obtained by;
grafting acrylonitrile on polystyrene, polyvinvyl chloride and vinyl perchloride showed that
the glass temperature Tc of these copolymers, regardless. of the ratio of the components,
corresponds essentially to the glass temperature of the initial polymers, but that the floAr
temperature T~ lies above the temperature of chemical stability of the products. Copolymers,
as compressed tablets (3-4 mm thick and 7 mm. in diameter), were tested before and after
Irradiation at doses of 1-10 Mr. 7be thermomechanical curves were plotted with the
dynamometric scales of Kargin and Sogolova, at a constant load for 10 sec. , at a: specific

load of 1. 4 kg/cm2. The curves obtained for all the copolymers, with or without plasticizers
were quite similar, and showed less effect of temperature than on pure polymers. Tabula-
ted irradiation data showed that the 'thermomechanical properties of grafted copolymers
remain almost unchanged under the influence of irradiation. This indicates the greater
stability of grafted copolymers to Y -rays as well as to high temperatures. The flow of
grafted copolymers is therefore considered to be almost Independent of grafting. An in-
~j vestigation of the plasticizing of grafted copolymers showed that grafted copolymers syn-
thesized from two homopolymers which have a common plasticizer remain unchanged in
their compatibility with this plasticizer. For grafted copolymers containing, on th one
hand, chains able to plasticize (polystyrene, polyvinyl chloride) and, in the other component,
;j unplasticizable rigid chains (polyacrylonitrile), the compatibility with the plasticizer is low 1
and limited. The change in thermomechanical properties (decrease in Tc) with increasing
plasticizer concentration (tetralin or methylbenzoic ether) to plotted. In addition,
analytical data for nitrogen content and acid number of the grafted copolymers are tabu-
lated. The thermomechanical curves of saponified vinyl perchloride and polyacrylonitrile
grafted copolymers showed that the glass temperature is decreased and the plasticity is
increased by saponification. A further Increase,,in plasticity is produced by plasticizers,
especially glycerol .. Such an increase could never be obtained by plasticizing unsaponified
grafted copolymers. Orig. art. has: 2 tables and 3 figures.
