<P>PROBLEM TO BE SOLVED: To provide an injection-molded article of polylactic acid, which has excellent heat resistance and the like. <P>SOLUTION: The injection-molded article comprises a stereocomplex polylactic acid containing a polylactic acid obtained by extending a chain by a polyisocyanate via an amide bond. The injection-molded article comprises a stereocomplex polylactic acid, such as a polylactic acid resin (A) having an amide bond obtained by making a composition containing a poly L-lactic acid (a-1) essentially comprising L-lactic acid and a poly D-lactic acid (a-2) essentially comprising D-lactic acid react with polyisocyanate. <P>COPYRIGHT: (C)2012,JPO&INPIT |
