Synthesis of Polycaprolactone Using Free/Supported Enzymatic and Non‐Enzymatic Catalysts
Abstract Summary: Polymerization of caprolactone using lipases from Candida antarctica B , Rhizomucor meihei, Candida rugosa , and Pseudomonas fluorescens is highly effective, with 97% conversion into polycaprolactone. Poly(propylene)‐supported Candida rugosa lipase achieves higher conversion values...

Summary: | Abstract Summary: Polymerization of caprolactone using lipases from Candida antarctica B , Rhizomucor meihei, Candida rugosa , and Pseudomonas fluorescens is highly effective, with 97% conversion into polycaprolactone. Poly(propylene)‐supported Candida rugosa lipase achieves higher conversion values (85–92%) than free lipase (75%). Acidic and basic non‐conventional catalysis with butanol yields 50–85% conversion. Simple UV/visible techniques gave the same results for measuring conversion than other studies. Applications are opened for the non‐conventional catalysts.
