Title:
PROCESS FOR ENZYMATIC HYDROLYSIS OF CYCLIC OLIGOMERS
Document Type and Number:
WIPO Patent Application WO2004016669
Kind Code:
A3
Abstract:
The present invention relates to a process for enzymatic hydrolysis of cyclic oligomers of poly(ethylene terephthalate), which process comprises subjecting the cyclic oligomer to the action of one or more lipolytic and/or biopolyester hydrolytic enzymes(s) and a nonionic, nonlinear surfactant.
