POLYLACTIC ACID COMPOSITION HAVING EXCELLENT HEAT RESISTANCE AND MOLDING CYCLE PROPERTY

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid composition having excellent heat resistance and molding cycle properties.;SOLUTION: The thermoplastic resin composition having the excellent heat resistance and molding cycle properties is produced as follows: Polylactic acid is compounded with a copolyester resin having a specific melting point together with a nucleating agent in order to improve the heat resistance of the polylactic acid and shorten the molding cycle. Thereby, the heat deformation resistance temperature can be improved and the molding cycle can further be shortened to that comparable to usual thermoplastic resins.;COPYRIGHT: (C)2008,JPO&INPIT
