WIPO Patent Application WO/2020/129663
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a polyacetal resin composition capable of keeping the generation of formaldehyde from a molded article at a very low level and stably keeping mold deposits at a minimum during molding. The purpose of the present invention is achieved by a polyacetal resin composition containing at least (A) 100 parts by mass of a polyacetal polymer, (B) 0.01-0.50 part by mass of an aliphatic carboxylic acid hydrazide, (C) 0.001-0.50 part by mass of a hydantoin compound having two hydrazinocarbonylalkyl groups, and (D) 0.001-0.30 part by mass of an alkaline earth metal salt of an aliphatic carboxylic acid, the polyacetal resin composition being such that the total amount of (B) and (C) is 0.03-0.55 part by mass per 100 parts by mass of the (A) polyacetal polymer.
