Low‐molecular‐weight polyesters were obtained by the ring‐opening homopolymerization and copolymerization reaction of ϵ‐caprolactone, rac ‐ or L ‐lactide, and glycolide in the presence of poly(ethylene glycol) with an enzyme catalyst, a lipase from Candida antarctica, Pseudomonas cepacia , or Pseudomonas fluorescens . The influence of several parameters, including time, temperature, and enzyme and monomer concentration, on the polymerization rate was studied. The resulting polymers were characterized by 1 H‐NMR or 13 C‐NMR, Fourier transform infrared spectroscopy, matrix‐assisted laser desorption/ionization–time of flight mass spectroscopy, and gel permeation chromatography. © 2012 Wiley Periodicals, Inc.
