Abstract: Methyl methacrylate(MMA) was random copolymerized with biphenyl methacrylate via group transfer polymerization.The copolymer composition was measured by 1HNMR,the thermal behaviour of these copolymer was determined by DSC. The reactivity ra-tios were r1=0.56±0.03,0.52±0.03,0.46±0.03 and r2=0.79±0.03,0.81±0.03,0.85±0.03 in benzene,tetrahydrofuran and acetonitrile respectively at 30℃. Copolymers withnarrow molecular weight distribution and predetermined molecular weight were obtained.

Key words: Group transfer copolymerization, Reactivity ratio, Methyl methacrylate, Biphenyl methcrylate
