BIODEGRADABLE LIGNEOUS ALIPHATIC POLYESTER RESIN COMPOSITION AND METHOD OF PRODUCING THE SAME

摘要

PROBLEM TO BE SOLVED: To obtain a biodegradable ligneous aliphatic polyester resin composition that has excellent mechanical performance, biodegradability and processability of molding. SOLUTION: The objective biodegradable polyester is obtained by formulating 30-200 pts.wt. of an organic filler, 0.1-7 pts.wt. of a lubricant and/or 1-50 pts.wt. of a plasticizer to 100 pts.wt. of an aliphatic polyester resin melting at 55-120 deg.C.
