POLYLACTIC ACID RESIN COMPOSITION, METHOD OF PRODUCING INJECTION-MOLDED ARTICLE, INJECTION-MOLDED ARTICLE, AND HOLDER FOR ELECTRONIC DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a polylactic acid resin composition containing a polylactic acid, wherein: thermal contraction with time is greatly prevented from occurring in the injection-molded article under a high-temperature environment without complicating manufacturing steps or causing cost increase; and the injection-molded article having good appearance can be formed.;SOLUTION: The polylactic acid resin composition comprises the polylactic acid, a polymethylmethacrylate resin, and an ABS resin. The ratio of the polylactic acid falls within the range of 3-40 mass%; and the ratio of the polymethylmethacrylate resin falls within the range of 0.5-17 mass%. The polylactic acid contains 8-15 mol% of D-lactic acid unit.;COPYRIGHT: (C)2012,JPO&INPIT
