Highly (S)-enriched substituted poly(¤-caprolactone)s were synthesized from 4-methyl-¤- caprolactone (4-MeCL)and 4-ethyl-¤-caprolactone (4-EtCL)by lipase Novozym-435 (from Candida antarctica)catalyzed ring-opening polymerizations. The polymerizations were performed in bulk, thus eliminating the need for solvents in the polymerization process. Poly(4-EtCL)and poly(4-MeCL)having >95
