    摘要:Disclosed are a zinc catalyst for catalyzing ring-opening polymerization of cyclic esters and controlled depolymerization of polyester materials and a catalytic method therefor, which belong to the technique for polymer synthetic materials and the technical field of polyester depolymerization. The invention solves the problems of the lack of environmental friendly technology for polyester synthesis and the lack of a mild and efficient recycling method for waste polyesters. The present invention uses an environmental friendly bis(hexaalkyl disilazane) zinc catalyst which does not need a ligand to participate. The zinc catalyst can achieve efficient and highly controllable active polymerization of different lactones under mild conditions, and has good universality of monomers, thereby obtaining various polyester materials having different structures. At the same time, by using the zinc catalyst in the present invention, with the participation of an alcohol compound, a polyester material is rapidly depolymerized into small organic molecules by means of a transesterification reaction catalyzed by the catalyst to realize the reuse of waste polyester, thereby realizing the real sustainable development and circular economy.
