Copolymers of p-bromophenyl acrylamide with methyl methacrylate were prepared and characterized using microanalysis and IR spectroscopy. The reactivity ratio values of the copolymerization were calculated using 1HNMR technique. Thermal analyses of the copolymers showed that the stability are intermediate between poly(Pbromo phenyl acrylamide) and poly (methyl methacrylate) homopolymers.
