Title:
BIODEGRADABLE POLYESTER RESIN COMPOSITION, METHOD FOR PRODUCING THE SAME, AND MOLDED BODY USING THE SAME
Document Type and Number:
Japanese Patent JP2008308562
Kind Code:
A
Abstract:
To provide a biodegradable polyester resin composition excellent in flexibility, gas permeability and moist thermal stability.
The biodegradable resin composition contains a biodegradable polyester resin and a rosin alcohol alkylene oxide adduct. The rosin alcohol alkylene oxide adduct is a random copolymer having a molecular weight of larger than 5,000 to 50,000, in which the alkylene oxide is a block of at least one or two kinds selected from ethylene oxide, propylene oxide and butylene oxide.
