摘要

Oxyanion-initiated polymerization has been greatly developed in recent years. The monomers have been expanded from methacrylate monomers with a a-positioned donor group in the ester moiety to oxetane monomers and methacrylate monomers with hydroxyl group, and some novel hybranched polymers are obtained. The new progress of oxyanion-initiated polymerization, and its mechanisms and applications in the synthesis of hybranched polymers are summarized in detail.
