METHOD FOR PRODUCING OXYMETHYLENE COPOLYMER RESIN COMPOSITION, AND OXYMETHYLENE COPOLYMER RESIN COMPOSITION

WIPO Patent Application WO/2022/091522

A1

The present invention provides a method for producing an oxymethylene copolymer resin composition, the method comprising a step in which an oxymethylene copolymer (A) is melt-kneaded together with an amine-substituted triazine compound (B), the amount of which is Mn μmol per g of the oxymethylene copolymer (A), choline hydroxide (C), the amount of which is Mc μmol per g of the oxymethylene copolymer (A), and an antioxidant (D), the amount of which is 0.05-1.1 parts by weight per 100 parts by weight of the oxymethylene copolymer (A), the Mn (μmol/g-POM) and Mc (μmol/g-POM) satisfying 6.5<(Mn+Mc×8)<25, 0.5
