1,1-双（乙氧基羰基）-2-乙烯基环丙烷（ECVCP）和甲基丙烯酸甲酯（MMA）的自由基共聚在 AIBN 存在下于 60°C 本体或氯苯中进行。共聚物的产率和分子量均低于均聚物。共聚物的结构分析表明自由基共聚通过开环然后分子内环化进行。通过Fineman-Ross法和非线性最小二乘法评估共聚参数分别为r 1 = 0.11，r 2 = 21.09和r 1 = 0.11，r 2 = 21.51（M 1 ，ECVCP；M 2 ，MMA）。
Radical copolymerization of 1,1-bis(ethoxycarbonyl)-2-vinylcyclopropane (ECVCP) and methyl methacrylate (MMA) was carried out in the presence of AIBN at 60°C in bulk or in chlorobenzene. Both the yields and molecular weights of the copolymers were lower than these of the homopolymers. Structural analysis of the copolymer suggested that radical copolymerization proceeded through ring opening followed by intramolecular cyclization. The copolymerization parameters were evaluated to be r 1 = 0.11, r 2 = 21.09 and r 1 = 0.11, r 2 = 21.51 (M 1 , ECVCP; M 2 , MMA) by Fineman-Ross and nonlinear least-squares methods, respectively
