用于环酯单体开环聚合的无金属引发/催化体系

Metal-Free Initiator /Catalyst Systems for the Ring Opening Polymerization of Cyclic Ester Monomers

环酯单体在不同引发/催化体系作用下的开环聚合是制备可生物降解脂肪族聚酯的主要方法。综述了近年来用于环酯单体开环聚合的无金属引发/催化体系,主要涉及水、醇、胺、羧酸等引发剂及质子酸、膦类、氮杂环类化合物等催化剂体系。

The ring opening polymerization （BOP） of cyclic ester monomers in the presence of various initiator/ catalyst systems is a main approach for the preparation of biodegradable aliphatic polyesters. The recent progress of metalfree initiator/catalyst systems used for the ROP of cyclic ester monomers is reviewed, including H2O, alcohol, amine, and carboxylic acid initiators, as well as proton acid, phosphine and N-heterocycle catalysts.
