摘要：

A study was conducted to synthesize polystyrene-block-poly(vinyl acetate) through a switchable reversible addition-fragmentation chain transfer (RAFT) agent. A new class of stimuli-sensitive switchable RAFT agents were found to offer better control over polymerization of more activated monomers (MAMs) and less activated monomers (LAMs). Efforts were made to synthesize polystyrene-block-poly(vinyl acetate) with these agents. Several approaches were investigated to synthesize polystyrene-block-poly(vinyl acetate) with the RAFT agent. The protonated RAFT agent 1-H+ was used to control the polymerization of styrene to form 1-H+ -PS. The macro-RAFT agent was neutralized, forming 1-PS and used in VAc polymerization to provide the desired 1-PS-PVAc.
