METHOD FOR CONTROLLING DEGRADATION OF BIODEGRADABLE POLYESTER AND DEGRADATION-CONTROLLED BIODEGRADABLE POLYESTER

摘要

The present invention relates to a method for controlling degradation of a biodegradable polyester, specifically to capping a carboxyl end of a biodegradable polyhydroxyalkanoate (PHA) or a copolymer thereof having a carboxyl group at one end, thereby suppressing degradation due to lyase, and thus allowing the benefit of facilitating suppression or control of degradation on the basis of the capping percentage of a carboxyl group.
