Polylactic acid resin composition and resin molded article thereof

摘要

Provided are a polylactic acid resin composition excellent in transparency, heat resistance, and migration resistance, and excellent in productivity at the time of the mold forming thereof, and a resin molded article thereof. The polylactic acid resin composition includes a polylactic acid; a reaction product of at least one selected from the group consisting of sorbitol, mannitol, and dehydration condensates thereof, an alkylene oxide mainly formed of ethylene oxide, and a fatty acid having 8 to 24 carbon atoms; and a fatty acid amide having a hydroxyl group.

1. A polylactic acid resin composition, comprising:
(i) a polylactic acid; (ii) a reaction product of:
at least one selected from the group consisting of sorbitol, mannitol, and dehydration condensates thereof,an alkylene oxide comprising ethylene oxide, wherein the ethylene oxide accounts for over half of the alkylene oxide, anda fatty acid comprising 8 to 24 carbon atoms, and (iii) a fatty acid amide comprising a hydroxyl group; wherein the fatty acid amide (iii) comprises a bisamide compound obtained by reacting a fatty acid comprising 8 to 24 carbon atoms and a hydroxyl group with a compound comprising two amino groups, wherein a content of the reaction product (ii) falls within a range of 0.5 to 10 parts by weight with respect to 100 parts by weight of the polylactic acid (i), and wherein a content of the fatty acid amide (iii) falls within a range of 0.1 to 0.7 parts by weight with respect to 100 parts by weight of the polylactic acid (i).
