The instant invention discloses a polylactic acid stereocomplex composition containing pure stereocomplex crystals and a process for its manufacture. The composition according to this invention comprising (a) 30-70 wt % poly (L-lactic acid) (PLLA). (b) 70-30 wt % poly (D-lactic acid) (PDLA) and (c) 0.01-10 wt % nucleating agent, which can be obtained by solution and melt blending. Stereocomplex crystals are preferentially formed according to the invention, and the homocrystals (a crystal form) for the PLLA or PDLA homopolymer can't be observed. The melting temperature of the composition according to the invention is at least 200&#xb0; C., which is about 30-50&#xb0; C. higher than the PLLA or PDLA homopolymer.
