氟烯烃共聚合的研究进展

概述了氟烯烃共聚物树脂的发展,总结了氟烯烃与其他单体共聚合的相关研究。大多数情况下,氟烯烃单体的共聚反应得到的是随机共聚物。虽然聚合反应涉及的含氟单体和共聚单体种类很多,但最终聚合物按其性能和应用主要包括热塑性体、弹性体和热塑性弹性体3类。通过筛选一些特定功能性的单体参与聚合反应,可以使得含氟聚合物的某些性能如溶解性、交联固化性、附着力等得到补偿。此外,文中列出了一些氟烯烃单体的Q-e参数,并从理论上讨论了共聚物的结构;简述了吸电子氟烯烃单体与供电子全质子单体间的交替共聚行为,并列举了具体实例。

Research progress in fluoroalkenes copolymerization

The development of fluoroolefin copolymer resins,and the relative researches on the copolymerization between fluoroalkenes and "dry" proton monomers are summarized.In most cases,random copolymers are obtained during the copolymerization of fluorinated alkenes.The types of fluorinated monomer and co-monomer are very much involved in polymerization reaction,however,finished products can mainly be divided into thermoplastic,elastomer,and thermoelatomer according to their performance and application.Some properties of fluoropolymer,such as solubility,cross-linking curability,adhesion,etc.,can be compensated by introducing some monomers with special function to the copolymerization system.In addition,the Q-e parameters of some fluorinated monomers are listed in this article.Finally,alternating copolymerization based on electron-withdrawing fluorinated monomer with electro-donating hydrogenated monomer is presented and illustrated with examples.
