1，1-二氰基-2-乙烯基环丙烷1在苯腈中进行自由基开环聚合，得到了可溶于有机溶剂的均聚物2，而在其他溶剂中则得到了不溶于水的交联型均聚物。此外，1还与1-氰基-1-酯-2-乙烯基环丙烷3和4进行了自由基共聚合，得到了相应的共聚物7和8。随着1-氰基-1-酯-2-乙烯基环丙烷含量的增加，共聚物在有机溶剂中的溶解度降低，600 °C时的残留量增加，玻璃化转变温度升高。2019威利期刊公司J.Polym。科学，A部分：多晶硅。化学。2019、57、1723-1729
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.
