Abstract
With porcine pancreatic lipase (PPL) as catalyst, aliphatic polyesters with hydroxyl and carboxyl end groups were synthesized through polycondensation of 3-hydroxybutyric acid (3-HBA) or 12-hydroxydodecanoic acid (12-HDA). Th e molecular weight ((M) over bar(n), number average) of obtained polymers v aries from several hundred to several thousand depending on monomer used an d reaction conditions as well. Resultant polymers were characterized by IR, H-1-NMR and GPC. (C) 1999 Elsevier Science Ltd. All rights reserved.
