【Abstract】 Biodegradable polyesters are polymer materials, they can be synthesized by chemical methods, enzymatic-catalysis and ferment. The recent progress of the enzymatic-catalysis synthesis methods of some biodegradable polyester is reviewed in this paper. Enzymatic-catalysis methods include ring-opening polymerization of lactones, step-growth polycondensation of diacids and diols, hydroxy acids and transesterification of diesters. Enzyme catalyzed synthesis of the polyesters is a new eco-friendly, mild and efficient technique. Moreover, specific enzyme catalysis can provide a novel synthetic route for useful polyesters, many of which are difficult to be synthesized by conventional methods.更多还原
