PROBLEM TO BE SOLVED: To provide a polylactic acid-containing polypropylene resin composition capable of forming moldings having excellent bending modulus, heat resistance and impact resistance; to provide a method for manufacturing the same and moldings prepared by molding the same. SOLUTION: The polylactic acid-containing polypropylene resin composition comprises 15 to 88.9 wt.% of component (A): a specific propylene-α-olefin block copolymer, 0.1 to 5 wt.% of component (B): an acid-modified polyolefinic and/or a hydroxy-modified polyolefinic resin, 10 to 50 wt.% of component (C): a specific polylactic acid-based resin, 0.5 to 10 wt.% of component (D): an epoxy-modified polyolefinic resin, and 0.5 to 20 wt.% of component (E), and has specific physical properties. Also there are provided a method for manufacturing the resin composition, and moldings of the resin composition. COPYRIGHT: (C)2011,JPO&INPIT |
