In vitro synthesis of polyesters by polycondensation using isolated enzymes as catalyst via nonbiosynthetic pathways is reviewed. In most cases, lipase was used as catalyst and the polyesters were obtained from oxyacids, their esters, and dicarboxylic acid derivatives/glycols. Enzymatic polymerization proceeded under mild reaction conditions in comparison with chemical processes. By utilizing characteristic...
Lipase-catalyzed synthesis of aliphatic polyesters has been achieved by using anhydride derivatives as starting substrate. Candida antarctica lipase efficiently catalyzed the dehydration reaction of polyanhydrides and glycols in toluene, yielding the corresponding polyesters. Effects of the reaction parameters on the polymer yield and molecular weight have been systematically investigated. The dehydration...
