| Abstract: | Summary Lipase-catalyzed polytransesterification ofbis(2,2,2-trifluoroethyl) dodecanedioate with aliphatic diols (from 1,2-ethanediol to 1,6-hexanediol) was studied with 4 enzymes and a number of solvents. The effects of experimental parameters were investigated with the purpose of obtaining a polyester of as high as possible average molar mass. The highest mass average molar mass (M
w) of 34,750 g mol-1 (DP = 122) was obtained under vacuum with 1,4-butanediol,Mucor miehei lipase, and diphenyl ether as solvent. |
