Investigations in the field of radiation-induced solid state polymerization-XXXI

Binary systems of N-vinyl succinimide and endomethylene tetrahydrophtalic acid monoallyl ester with some additives were studied. It was established that the amount and nature of the quasi-eutectic structure could be regulated to the desired extent only when crystallization was performed under nearly isothermal conditions. In the present conditions for heat transfer, one component of the binary system should have a maximum linear crystallization rate low enough to produce a maximum linear crystallization rate of the quasi-eutectic structure less than 1 × 10^?2 mm/sec. In many cases, kinetic results could definitely be connected with qualitative and quantitative changes in the quasi-eutectic structure. Some phenomena suggested the roles of certain structural features and the phase conditions of the ternary system formed by the polymer produced.
