SYNTHESIS OF POLY(5,5-DIMETHYL-1,3-DIOXAN-2-ONE)BY LIPASE-CATALYZED RING-OPENING POLYMERIZATION*

Received Date: 30 August 2002
Revised Date: 18 September 2002

Porcine pancreas lipase (PPL) and PPL immobilized on narrow distributed micron-sized glass beads wereemployed successfully for the ring-opening polymerization of 5, 5-dimethyl-1, 3-dioxan-2-one (DTC) for the first time.Different polymerization conditions such as enzyme concentration and reaction temperature were studied. Immobilized PPLexhibits higher activity than native PPL. Along wth the increasing enzyme concentration, the molecular weigh of resultingPDTC decreases. PPL immobilized on narrow distributed micron-sized glass beads has outstanding recyclability.For the third recycle time,immobilized PPL exhibits the highest catalytic activity and with high activity even after the fifth recyle time for the synthesis of PDTC.The 1H-NMR spectra indicate that decarboxylation does not occur during the ring-opening polymerization.
