METHOD OF MANUFACTURING POLYESTER RESIN MOLDED ARTICLE, CRYSTALLIZATION INDUCING AGENT FOR USE THEREIN, MASTER BATCH, AND POLYESTER RESIN MOLDED ARTICLE

摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a crystallized polyester resin molded article not impairing transparency by dispensing with an inorganic crystal nucleus agent.

SOLUTION: The method of manufacturing a crystallized polyester resin molded article comprises: melt-injecting a mixture (a compound) of the following (a) or (b) into a mold and holding the mixture in a mold; thereafter cooling to crystallize a polyester resin constituting the molded article without using an inorganic crystal nucleus agent. (a) A mixture of a crystallization-inducible crosslinked polyester resin A having a crosslinked point formed at at least a part therein by using a crosslink-forming agent and a non-crosslinked polyester resin C. (b) A mixture of a mixture (a crystallization-inducible master batch M) of the resin A and a non-crosslinked polyester resin B which contains the resin A in a larger quantity, and a non-crosslinked polyester resin C.
