✦ Synopsis

Abstract

A novel fluorine‐containing polymer, poly[N‐(2,3,4,5,6‐pentafluorophenyl)maleimide], was prepared by the anionic polymerization of N‐(2,3,4,5,6‐pentafluorophenyl)maleimide (PFPMI). Anionic polymerization with alkali metal tert‐butoxides gave poly(PFPMI) in 14–32% yield. Phenyllithium and sec‐butyllithium also afforded poly(PFPMI). No polymer was obtained with a radical initiator such as 2,2′‐azoisobutyronitrile. The polymerization took place only via the vinylene group of PFPMI and no appreciable side‐reaction occurred. The obtained poly(PFPMI) shows unimodal molecular weight distribution and begins to decompose at 325°C.
