ABSTRACT: The copolymerization of styrene with N-methacryloyleapro-
lactam, (HACL) has been investigated. The optimum copolymerization
conditions wereestablished. The empirical dependence of the HACL in
the copolymer on the amount in the feed mixture was found. The re-
activities of these monomers during copolymerization in c-caprolactam,-
solution were determined, The chain transfer constant through e-capro-
lactam.. was determined, It is shown that c-caprolactamv does not con-
siderably affect thechain growth and that it is a suitable solvent

ABSTRACT- N, N1, N"-trimesinoyl-ter-caprolactame has been synthesized and was shown
to be an effective activator of anionic polymerization of F--caprolactame, making it
possible to produce insoluble polymers. The physical and mechanical propertiesAf
these polyamides were analyzed. It was found that they have higher elasticityj-~nd
impact strength properties than those of linear polyamides prepared in the presence
of monofunctional activators. It is shown that the use of a trifunctional activator
leads to the formation of brfinched and crosslinked polyamides. Orig. art. has:

ABSTRACT: The continuous.search in the USSR for thermostable and heat-resistant-
polymers prompted a study ofthe thermal stability of some newly synthe-sized
1'pblybenzimidazoles. The subjects of the study were the polymers obtained
from 3. 3'I -dia-minobenzidine with directly connec.ted benzimidazole groups.
~d those obtained. from 3, 31, 4, 41 -tetraaminodiphenylmethane with benz-
a
irqidazole groups connected by a -C112- bridge. Tho polyme *r-s studied are
shown in the two following tables. Table I contains data on polybenzimid zples
1with aliphatic chains, while Table 2 fully describes aromatic polybenz-
imidazoles or those with heteroatoms in their structure. The synthesis of
1,~ese polymers was reported previously.
