PRODUCTION METHOD FOR MOLDED MEMBER HAVING IMPROVED HYDROLYSIS RESISTANCE AND PRODUCED FROM POLYAMIDE MOLDING MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a production method for a molded member having improved hydrolysis resistance and produced from a polyamide molding material.SOLUTION: There is provided a method of producing a molded member in the condensation of the polyamide molding material, which method comprises (a) a step of preparing the polyamide molding material in which at least 50% of the terminal group of the polyamide is present as an amino group; (b) a step of producing a mixture of the polyamide molding material and 0.1-5 mass% oligocarbodiimide or polycarbodiimide based on the amount of polyamide molding material, in which condensation is not practically performed here; (c) a step of optionally storing and/or transporting the mixture; and (d) a step of successively processing the mixture to produce a molded member, in which condensation is performed for the first time.
