Lipase-Catalyzed Ring-Opening Polymerization of Cyclic Diesters

Ring-opening polymerization of cyclic diesters, ethylene dodecanedioate and ethylene tridecanedioate, took place using lipases as a catalyst under mild reaction conditions to give the corresponding polyesters with molecular weight of several thousands. Enzymatic polymerizability of these new monomers was compared with that of lactones.
