Abstract:
PROBLEM TO BE SOLVED: To obtain a resin composition excellent in moldability, durability and chemical resistance, and, in a preferable embodiment, excellent in toughness and heat resistance, and to provide a molded product made from the composition. SOLUTION: The resin composition is obtained by compounding 100 pts.wt. of a polylactic acid resin with less than 100 pts.wt. of a thermoplastic resin other than the polylactic acid resin. This resin composition has such a phase structure that the polylactic acid resin and the other thermoplastic resin represent dispersed phase and continuous phase respectively. The molded product made from the resin composition is also provided. In this resin composition, it is preferable that the ratio of the melt viscosity of the polylactic acid resin to that of the other thermoplastic resin be greater than 1, wherein the melt viscosity is measured at 190°C and at a shearing rate of 60 s -1 , and the other thermoplastic resin be a polyolefin resin, especially including polypropylene resin.
