ABSTRACT:
The present invention relates to a polylactic acid resin composition. The composition includes about 25 to about 80 parts by weight of a polylactic acid resin, (B) about 20 to about 75 parts by weight of a polycarbonate resin, and (C) about 0.01 to about 5 parts by weight of a chain extender including an amine group, based on about 100 parts by weight of (A)+(B). The polylactic acid resin composition of the present invention is environmentally-friendly and has excellent hydrolysis resistance and simultaneously improved mechanical strength and heat resistance, and accordingly can be used for manufacturing various molded products requiring heat resistance and mechanical strength, for example vehicles, machine parts, electronic parts, office machines, miscellaneous goods, and the like.
