<P>PROBLEM TO BE SOLVED: To provide a resin composition which prevents isolation of a compound having an isocyanate group by blending a resin component comprising polylactic acid and aromatic polycarbonate with less environmental load, a cyclic carbodiimide compound having a carbodiimide group in a cyclic structure, and an antioxidant, and which is good in working environment and is excellent in chemical resistance and impact resistance as well as hydrolysis resistance. <P>SOLUTION: The resin composition contains (B) 0.001-10 pts.wt. of a compound (component B) which comprises a cyclic structure having one carbodiimide group and whose first and second nitrogens are bound to each other via a linking group, the cyclic structure being expressed by the formula (1), and in which the number of atoms forming the cyclic structure is 8 to 50, and (C) 0.001-2 pts.wt. of at least one antioxidant (component C) selected from the group consisting of compounds of phosphite, phosphonite, hindered phenol and thioether, based on (A) 100 pts.wt. of the resin component (component A) comprising 5-95 wt.% polylactic acid (component A-α) and 95-5 wt.% aromatic polycarbonate (component A-β). <P>COPYRIGHT: (C)2012,JPO&INPIT |
