Abstract
The present invention provides the method for producing a polylactic acid resin composition, including steps (1) and (2)step (1): adding the polycarbodiimide cross-linking agent to the polylactic acid resin to cross-link the polylactic acid resin; andstep (2): mixing the cross-linked polylactic acid resin prepared in the step (1) with the uncross-linked polylactic acid resin.
