Title:
POLYACETAL RESIN COMPOSITION AND PRODUCTION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2021/039003
Kind Code:
A1
Abstract:
The purpose of the present invention is to improve the mechanical strength of a polyacetal resin, in particular, the tensile strength and the bending strength. The purpose of the present invention is achieved by a polyacetal resin composition that is obtained by blending at least: (A) 100 parts by mass of a polyacetal resin; (B) 0.01-1.0 part by mass of a hindered phenol-based antioxidant; (C) 1-100 parts by mass of a glass fiber; and (D) 0.1-20 parts by mass of a copolymer obtained by polymerizing (a) trioxane, (b) a cyclic acetal compound having an oxyalkylene group having 2 or more carbon atoms in a ring, and (c) a silicon compound having an alkoxy group bonded to silicon.
