Abstract
A method for synthesizing a polyester comprises reacting a diester and a dialcohol at approximately ambient temperature in the presence of an enzyme catalyst, preferably a lipase comprising porcine pancreatic lipase. The method is particularly adapted for enantioselective polymerization resulting in an optically active polyester. The polyesters preferably exhibit a weight average molecular weight, Mw, as measured by gel permeation chromatography of at least about 3000.
