PROBLEM TO BE SOLVED: To provide an environmentally compatible polylactic acid resin composition having excellent heat resistance and appearance and improved weld impact strength.;SOLUTION: This invention relates to the environmentally compatible polylactic acid resin composition. The polylactic acid resin composition comprises (A) a base resin comprising (a1) a polylactic acid (PLA) resin and (a2) a polycarbonate resin and (B) a compatibilizer which can form a stereocomplex together with the polylactic acid (PLA) resin. The environmentally compatible polylactic acid resin composition as an environmentally compatible resin composition can has excellent appearance, improved weld impact strength and as well improved mechanical strengths and heat resistance and can be usefully used in the production of molded articles, such as automobile components, machine parts, electrical and electronic components, office machines, and sundries, which require heat resistance and mechanical strengths.;COPYRIGHT: (C)2010,JPO&INPIT
