A process for the production of a polylactic acid resin composition, which comprises a step (1) of wet-pulverizing an organic nucleating agent in the presence of a carboxylic ester that has a weight-average molecular weight of 150 to 600 and a viscosity of 1 to 500mPa·s at 23°C and/or a phosphoric ester that has a weight-average molecular weight of 150 to 600 and a viscosity of 1 to 500 mPa·s at 23°C to prepare a pulverized organic nucleating agent composition, and a step (2) of melt-kneading together the pulverized organic nucleating agent composition obtained in the step (1) and a polylactic acid-resin-containing raw material for a polylactic acid resin composition. The polylactic acid resin composition obtained by the process is suitable for various industrial uses such as daily goods, household appliance parts, packing materials for household appliance parts, and automobile parts. |
