PROCESS FOR PRODUCTION OF INJECTION-MOLDED ARTICLE OF POLYLACTIC ACID RESIN

摘要

A method of manufacturing a polylactic acid resin injection molded article, having the step (1): a step of melt-kneading a polylactic acid resin composition containing a polylactic acid resin and a specified organic crystal nucleus agent, while contacting the composition with a supercritical fluid; and step (2): a step of filling the melted product obtained in step (1) in a die to mold with injection-molding. The manufacturing method of the present invention is used as an advantageous technique as compared with the technique of achieving satisfactory moldability by the addition of plasticizer in the field, for example, which requires a polylactic acid resin molded article having high rigidity.
