✦ Synopsis

Abstract

Novel copolymers consisting of 3,3,3‐trifluoro‐1,2‐epoxypropane (TFEP) and N‐phenylmaleimide (PMI) units were prepared by the copolymerization of TFEP with PMI initiated with an organozinc compound. Using [Zn(OCH~3~)~2~ · (C~2~H~5~ZnOCH~3~)~4~] as an initiator, the copolymer chains consisted mainly of TFEP‐TFEP sequences. The TFEP‐PMI sequence content in the copolymer chains was small. On the other hand, using (C~2~H~5~ZnOCH~3~)~4~ as an initiator, only low molecular weight copolymers were formed. Those copolymers were suggested to have block structure, poly(TFEP)‐block‐poly(PMI), by the ^19^F NMR analysis. The copolymers showed higher thermostability than poly‐(TFEP).
