One‐Pot Difunctionalization of Poly(<i>ω</i>‐pentadecalactone) with Thiol‐Thiol or Thiol‐Acrylate Groups, Catalyzed by <i>Candida antarctica</i> Lipase B

Abstract

Abstract Summary: An enzymatic one‐pot procedure has been developed for the synthesis of difunctional polyesters containing terminal thiols and acrylates. Candida antarctica lipase B was used as a catalyst for the ring‐opening polymerization of ω ‐pentadecalactone. The polymerization was initiated with 6‐mercaptohexanol, then terminated with γ ‐thiobutyrolactone or vinyl acrylate to create two types of difunctional polyesters with a very high content of thiol‐thiol or thiol‐acrylate end‐groups.
