The characteristics of copolymerization of 5-vinyl-2-norbornene(ENB) and tert-butyl methacrylate(TBMA) catalyzed by Fe(acac)3-Al(i-Bu)3 were investigated.The copolymer composition was characterized by means of IR,NMR,and the relative molecular weight and relative molecular weight distribution of the copolymer were determined by gel permeation chromatography.The results show that the molar fractions of 5-vinyl-2-norbornene(ENB) and tert-butyl methacrylate(TBMA) in the copolymer were respectively 18.2% and 81...
