Title:
METHODS FOR SLOWING THE DEGRADATION RATE OF BIODEGRADABLE POLYMER AND BIODEGRADABLE POLYMER COMPOSITIONS AND COMPOSITIONS THEREOF
Document Type and Number:
WIPO Patent Application WO2002022737
Kind Code:
A3
Abstract:
The invention provides a biodegradable polymer composition comprising a biodegradable polymer and a phenol-containing compound mixed with the polymer. The phenol-containing compound is present in the biodegradable polymer at an amount sufficient to slow the degradation rate of the biodegradable polymer. The invention also pertains to a method for slowing the degradation rate of a biodegradable polymer.
