摘要
Oxiranes, such as glycidyl phenyl ether (GPE) and benzyl glycidate (BG), were copolymerized with succinic anhydride (SA) by lipase at a temperature between 60 and 80 degrees C to yield the corresponding polyesters bearing carboxyl or phenyl groups. Bulk polymerization, especially at the temperature of 80 degrees C, and preferably using porcine pancreatic lipase gave biodegradable polyesters with a molecular weight greater than 5000.
