Research Progress of Ring-opening Polymerization of ε-caprolactone Initiated by Degradable Biopolymers

The article reviews the research progress in the preparation of polycaprolactone through the ring-opening polymerization of ε-caprolactone initiated by biopolymers in recent years. The structure characteristics of starch, cellulose, chitosan, polyhydroxyalkanoates, and polylactic acid, the reaction mechanism, the preparation method, and the application of ε-caprolactone are introduced. Finally, the future development of new polycaprolactone copolymers is prospected.
