摘要 |
The present invention relates to a polylactic acid resin composition. The composition includes 25 to 80 parts by weight of a polylactic acid a resin, (B) 20 to 75 parts by weight of a polycarbonate resin, and (C) 0.01 to 5 parts by weight of an amine group-containing chain extender based of 100 parts by weight of the (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 thereby can be used for manufacturing various molded products requiring heat resistance and mechanical strength, for example a vehicle, machine parts, electronic parts, office machines, miscellaneous goods, and the like.
