Method of manufacturing crystallized polyester resin molded product, polyester resin molded product for compound, and crystallization polyester resin molded product

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.;COPYRIGHT: (C)2009,JPO&INPIT
