Abstract
Copolymerizations of vinyl chloride (VC) with N-vinyl-carbazole (NVC), acenaphthylene (ANT) and glycidyl methacrylate (GMA) were carried out. The values of r1 and r2 were computed as follows.
VC (M1), NVC (M2); r1=0.17 r2=4.77
VC (M1), ANT (M2); r1=0.001 r2=64
VC (M1), GMA (M2);r1=0.04 r2=8.84
It was found that the softening points of the copolymers with NVC and ANT were higher than that of polyvinyl chloride. It was found that the component of the copolymer GMA retards the coloring of PVC by heating. The copolymer reacts with diamines, dicarboxylic acid and mineral acids to give crosslinked polymers.
