Title:
POLYACETAL RESIN COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2023/136298
Kind Code:
A1
Abstract:
The present invention provides: a polyacetal resin composition that achieves a highly dispersed state of cellulose in a polyacetal resin, and that achieves, at a high level, both high temperature rigidity and toughness when being under a load; and a method for producing same. This polyacetal resin composition contains: 100 parts by mass of a polyacetal resin (a); 1-150 parts by mass of fine cellulose fibers (b) having a fiber diameter of 2-1000 nm; and 0.1-100 parts by mass of a polyethylene glycol (c). An ethylene ratio R (%) which is the ratio of the number of oxyethylene units in the polyacetal resin (a) with respect to the total number of oxymethylene units and oxyethylene units in the polyacetal resin (a), and an oxyethylene repeating unit number n of the polyethylene glycol (c) satisfy the relationship of formula: (R+0.5)/0.015 ≤ n ≤ (R+10)/0.015.
