POLYESTER RESIN COMPOSITION, PROCESS FOR PRODUCTION OF THE COMPOSITION, AGENT FOR PROMOTION OF CRYSTALLIZATION OF POLYESTER RESIN, AND MOLDED ARTICLE

摘要

Disclosed are: a crystallized polyester resin composition comprising at least one polyester resin A which has been crosslinked with at least one radical generator and at least one polyester resin B which is the same as or different from the polyester resin A and has not been crosslinked, wherein both of the resin A and the resin B are molten/mixed and crystallized homogeneously; a process for producing the composition; an agent for promoting the crystallization of a polyester resin; and an molded article. It becomes possible to provide: an agent for promoting the crystallization of a polyester resin, which has good compatibility with a polyester resin such as polylactic acid in which the crystallization do not proceed rapidly after molding, can provide a molded article having no white turbidity which is induced by a nucleating agent, can provide an molded article which can keep translucency provided only as a result of the light scattering caused by the crystallization of the resin, can accelerate the crystallization rate of the polyester resin after molding; and others.
