Abstract
The synthesis of degradable polymers with easy-to-break in-chain carbon-oxygen bonds has attracted much attention.This minireview introduces the synthesis of a variety of degradable polymers from the(co)polymerizations of several typical oxygenated monomers such as epoxides,cyclic carbonates,cyclic esters,carbon dioxide(CO2),carbonyl sulfide(COS),and cyclic anhydrides.We highlight the catalysts and mechanisms for these(co)polymerizations.The ring-opening copolymerization of five-membered carbon-ate with cyclic anhydride or COS has been introduced.We also highlight the synthesis of block copoly-mers and cyclic copolymers with well-defined sequences by the method of growing center switching.We hope that these new polymerization systems can provide new ideas for the development of degradable low-carbon polymers in the future.
