COMB-LIKE COPOLYMERS OBTAINED BY COPOLYMERIZATION OF 2-AMINO-4-(N-ALKYLANILINO)-6-ISOPROPENYL-1,3,5-TRIAZINES

Copolymerizations of 2-amino-4-(N-alkylanilino)-6-isopropenyl-1,3,5-triazines with styrene, methyl methacrylate and methyl acrylate were carried out using azobisisobutyronitrile as an initiator. Alkyl groups were propyl, hexyl, octyl, decyl, dodecyl, tetradecyl, hexadecyl, octadecyl, and docosyl. Copolymerization parameters (r1, r2, Q, and e) were determined for these monomers. No significant effect of alkyl chain length on the copolymrization parameters could be observed. Relationships between glass transition temperatures and composition of the copolymers were investigated. Crystallization exothermic and melting endothermic peaks due to the side-chains were observed in the DSC thermograms of thecomb-like copolymers containing octadecyl and docosyl groups. Thecrystallinity of the side-chains decreased with increasing content of styrene or methyl methacrylate in the copolymers. © 1990, The Society of Polymer Science, Japan. All rights reserved.
