Abstract
A polylactic acid resin composition containing 100 parts by weight of a polylactic acid compound (A) having a specific moiety represented by the formula (1): —X—R—X— and having a weight average molecular weight (Mw) of 5,000 to 500,000, 5 to 2,000 parts by weight of a lactic acid resin (B) and 0.1 to 10 parts by weight of at least one kind of a transparent nucleating agent (C) selected from carboxylic acid amides, aliphatic alcohols and aliphatic carboxylic acid esters. In the formula (1), X, Xand Rare defined. The resin composition can exhibit improved heat resistance (high crystallinity) and transparency without impairing the rigidity of the polylactic acid resin. A molded article composed of the resin composition is also provided.
