Methyl methacrylate(MMA)was statistically copolymerized with biphenyl methacrylate(BPMA)via group transfer polymerization.The copolymer composition was measured by 1H NMR
the thermal behaviour of these copolymer was determined by DSC.The reactivity ratios were γ 1 =0.56±0.03
0.52±0.03
0.46±0.03 and γ 2 =0.79±0 03
0.81±0.03
0.85±0.03 in benzene
tetrahydrofuran and acetonitrile respectively at 30℃.Copolymers with narrow molecular weight distribution and predetermined molecular weight were obtained.
