Lipase-catalyzed synthesis of aliphatic polyesters in supercritical carbon dioxide

Abstract Synthesis of aliphatic polyesters has been examined using Candida antarctica lipase in supercritical carbon dioxide (scCO 2 ). The enzymatic ring-opening polymerization of ε-caprolactone (ε-CL) proceeded in scCO 2 to give a polymer with molecular weight higher than 104. Effects of reaction...

Description
Summary:Abstract Synthesis of aliphatic polyesters has been examined using Candida antarctica lipase in supercritical carbon dioxide (scCO 2 ). The enzymatic ring-opening polymerization of ε-caprolactone (ε-CL) proceeded in scCO 2 to give a polymer with molecular weight higher than 104. Effects of reaction parameters such as the monomer concentration, enzyme amount and pressure have been systematically investigated. Copolymerization of ε-CL with 12-docecanolide afforded the random copolymer. The enzymatic polycondensation of divinyl adipate and 1,4-butanediol also proceeded in scCO 2 to produce the corresponding polyester.
