Abstract
A series of new isopropenyl-1,3,5-triazines, that is, 2-amino-4-(m-acylaminoanilino)-6-isopropenyl-1,3,5-triazine (AnIT, where “n” means the number of carbon atoms in the acyl group) was synthesized from the reaction of 2-amino-4-(m-aminoanilino)-6-isopropenyl-1,3,5-triazine with various acyl chlorides, including acetyl to octadecanoyl. These monomers were polymerized and copolymerized with styrene or methyl methacrylate in dimethyl sulfoxide using AIBN as an initiator, and copolymerization parameters (r1, r2, Q, and e values) of these monomers (M2) were determined. Glass transition temperatures of the homopolymers of A6IT through A18IT were around 182°C. The long acyl side-chains of poly(A16IT) and poly(A18IT) could crystallize and their melting temperatures were −21°C and 9°C, respectively. The crystallinity of the side-chains decreased with increasing content of styrene or methyl methacrylate in the copolymers.
