POLYLACTIC ACID RESIN COMPOSITION AND MOLDED OBJECT THEREOF

摘要

A polylactic acid resin composition capable of giving polylactic acids from which stereocomplex crystals of poly(L-lactic acid) and poly(D-lactic acid) are selectively crystallized at a sufficiently high rate to attain a high stereocomplex crystal proportion; and a molded object obtained by melt-molding the composition and crystallizing it. The polylactic acid resin composition is characterized by comprising polylactic acids capable of generating stereocomplex crystals and an aromatic urea compound represented by the following general formula (1): [Chemical formula 1] (1) wherein R<1> represents C1-10 alkylene; R<2> represents C1-25 alkyl; and m is an integer of 1 to 6.
