PROCESS FOR PRODUCTION OF MOLDED POLYLACTIC ACID RESIN ARTICLE, COMPOUND COMPRISING A CRYSTALLIZATION-INDUCING MASTER BATCH FOR USE IN THE PROCESS, AND MOLDED POLYLACTIC ACID RESIN ARTICLE

摘要

This invention provides a process for producing a crystallized polyester resin molding. The process includes melting and injecting the below-described compound (a) or (b) into a mold and holding the same in the mold, and then conducting cooling to crystallize a polyester resin of a resulting molding without using an inorganic nucleating agent: (a) a compound of a crystallization-inducing crosslinked polyester resin A, in at least a portion of which crosslinked points have been formed with a crosslink forming agent, and a non-crosslinked polyester resin C; or (b) a compound of a compound (a crystallization-inducing master batch M), which comprises the resin A and a non-crosslinked polyester resin B and abundantly contains the resin A, and the non-crosslinked polyester resin C. According to the present invention, a crystallized polyester resin molding free from impairment of transparency can be produced without using an inorganic nucleating agent that would produce haze in the molding.
