ADVANCES IN CONTROLLED/LIVING RADICAL POLYMERIZATION, cilt.854, ss.383-393, 2003 (SCI-Expanded)
The present work describes synthesis of well-defined polymeric photoinitiators via atom transfer radical polymerization (ATRP) and ring-opening polymerization (ROP) and their subsequent use in photoinduced block copolymerization. The first step of the process involves controlled polymerization of styrene and epsilon-caprolactone by using appropriate initiators possessing photolabile groups as well as functionality for ATRP and ROP, respectively. By selecting corresponding initiator and modifying the polymerization conditions, end-chain polymeric photoinitiators with various molecular weights and low polydispersities were obtained. These polymers were used in photoinduced free radical promoted cationic polymerization resulting in the formation of block copolymers.
