The ethylenes when copolymerized with styrene in solution with radical initiation (ABCN) at 70ˇăC resulted in formation of copolymers. The composition of the copolymers was calculated from nitrogen analysis. The structures and properties were characterized by IR, 1H and 13C-NMR, GPC, DSC, and TGA %U http://www.ccsenet.org/journal/index.php/ijc/article/view/0/39149
