Synthesis of block copolymers by mechanistic transformation from photoinitiated cationic polymerization to a RAFT processElectronic supplementary information (ESI) available. See DOI: 10.1039/c7py01707c

A novel synthetic strategy for the synthesis of block copolymers based on mechanistic transformation from photoinitiated cationic polymerization to radical addition fragmentation transfer polymerization is presented. The process yielded polytetrahydrofuran- b -poly(methyl methacrylate), which was fully characterized by spectroscopic, chromatographic and thermal analyses.
