Abstract

A novel well‐defined triblock copolymer containing perfluorocyclobutyl group was prepared by the combination of mechanism transformation strategy, thermal cycloaddition [2Π+2π] polymerization and atom transfer radical polymerization (ATRP). Firstly, a macroinitiator with two ATRP initiating end groups was synthesized by thermal polymerization of 4,4′‐bis‐(trifluorovinyloxy)biphenyl (BTFVBP) and sequential end‐capping with a difunctional compound containing trifluorovinyl and ATRP initiation group. Secondly, this macroinitiator initiated ATRP of t‐butyl acrylate to synthesize P__t__BA‐b‐PBTFVBP‐b‐P__t__BA triblock copolymer. This copolymer was hydrolyzed to afford PAA‐b‐PBTFVBP‐b‐PAA amphiphilic triblock copolymer. This kind of fluorine‐containing well‐defined structure should benefit the study of self‐assembly behaviors.

The anionic random copolymerization of methyl methacrylate (MMA) and 2-(1-acetoxyethoxy)ethyl methacrylate (AEEMA) was carried out using 1,1-diphenylhexyllithium (DPHL) as initiator, in the presence of LiCl ([LiCl]/[DPHL] 0 = 2), in tetrahydrofuran (THF), at -60 8C. The resulting polymer, poly-(MMA-
