Document Type and Number:
WIPO Patent Application WO/2012/099017
Kind Code:
A1
Abstract:
The present invention is a biodegradable resin composition which contains a hardly hydrolyzable biodegradable resin (A) and an ester degradation accelerator (B), and is characterized in that a copolyester, which contains a hardly hydrolyzable polyester segment (X) and a readily hydrolyzable polyester segment (Y) at a weight ratio such that 75/25 < X/Y < 10/90, is blended as the ester degradation accelerator (B). The biodegradable resin composition of the present invention has excellent biodegradability and excellent transparency.
