ABSTRACT:
A linear polyester is made by a process reacting polyols comprising at least two primary alcohol groups and at least one secondary alcohol or amino group and a dicarboxylic acid or a dicarboxylic acid ester in the presence of an effective amount of a lipase derived from Candida cylindracea, Candida lipolytica, Candida rugosa, Candida antarctica, Candida utilis, Chromobacterium viscosum, Geotrichum viscosum, Geotrichum candidum, Mucor javanicus, Mucor miehei, Porcine pancreas, Pseudomonas species, specifically Pseudomonas fluorescens, Pseudomonas cepacia, Pseudomonas pseudoalkaligenes, Pseudomonas alkaligenes, Thermomyces species, Rhizopus arrhizus, Rhizopus delemar, Rhizopus niveus, Rhizopus oryzae, Rhizopus javanicus, Aspergillus niger, Penicillium roquefortii, Penicillium camembertii or an esterase derived from Bacillus species, specifically Bacillus thermoglucosidasius; Mucor miehei, Horse liver, Saccharomyces cerevisiae, Pigs liver or combinations thereof. The secondary OH or amino group of the polyol moiety is unreacted.
