Radical ring‐opening polymerization of 1,1‐dicyano‐2‐vinylcyclopropane 1 was performed in benzonitrile to find the corresponding homopolymer 2 soluble in organic solvents was successfully obtained while that in other solvents gave crosslinked and thus insoluble homopolymer. In addition, 1 underwent radical copolymerization with 1‐cyano‐1‐ester‐2‐vinylcyclopropanes 3 and 4 to afford the corresponding copolymers 7 and 8. By increasing the content of the 1‐derived unit in the resulting copolymers, the solubility of the copolymers in organic solvents became lower and the residual weights at 600 °C and their glass transition temperatures became higher. © 2019 Wiley Periodicals, Inc.

1,1-二氰基-2-乙烯基环丙烷的自由基开环聚合行为及其与1-氰基-1-酯-2-乙烯基环丙烷的共聚合

在苯甲腈中进行了1,1-二氰基-2-乙烯基环丙烷1的自由基开环聚合反应，发现成功获得了可溶于有机溶剂的相应均聚物2，而在其他溶剂中则得到了交联且因此不溶的均聚物。另外，将1与1氰基-1-酯-2-乙烯基环丙烷3和4进行自由基共聚，得到相应的共聚物7和8。通过增加1的内容在所得共聚物中衍生出的单元中，共聚物在有机溶剂中的溶解度变低，在600°C时的残余重量和它们的玻璃化转变温度变高。©2019 Wiley Periodicals，Inc.J.Polym。科学，A部分：Polym。化学 2019，57，1723–1729
