  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. values (85–92%) than free lipase (75%).
