<br/><br/> In this paper, Novozyme-435-catalyzed ö-pentadecalactone and ö-pentadecalactone/¤- caprolactone polymerizations were investigated. Novozyme-435-catalyzed ö-pentadecalactone polymerizations were studied in bulk and at ö-pentadecalactone-to-toluene ratios from 1:1 to 1:10 (wt/vol). By carrying out polymerizations with ö-pentadecalactone to toluene 1:1 wt/vol instead of in bulk, the monomer conversion (32 to 90
