Abstract

Abstract: Enzyme-catalyzed polyester synthesis has been investigated with special emphasis on modulation of polymer molecular weight and dispersity. Supercritical fluids were also used for isolating low-dispersity polyester fractions by changing pressure. Enzymatic synthesis of low-dispersity polyesters was achieved in supercritical fluoroform. The synthesized polymer molecular weight can be controlled by changing the pressure.
