Abstract
To provide a polyacetal resin composition excellent in friction and abrasion resistance properties by improving the compatibility, dispersibility and interfacial adhesion between the polyacetal resin and an olefinic polymer. The polyacetal resin composition comprises: (A) 100 parts by weight of a polyacetal resin; (B) 0.5 to 100 parts by weight of a specified, modified olefinic polymer; (C) 0.01 to 10 parts by weight of an alkylene glycol polymer containing a primary or secondary amino group(s) and having a number-average molecular weight of 400 to 500,000; and (D) 0.1 to 20 parts by weight of an inorganic filler.

A polyacetal resin composition comprising:
- (A) 100 parts by weight of a polyacetal resin,
- (B) 0.5 to 100 parts by weight of a modified olefinic polymer obtained by modifying an olefinic polymer (B-1) with at least one member selected from the group consisting of unsaturated carboxylic acids and acid anhydrides thereof and derivatives thereof (B-2),
- (C) 0.01 to 10 parts by weight of an alkylene glycol polymer containing a primary or secondary amino group(s) and having a number-average molecular weight of 400 to 500,000, and
- (D) 0.1 to 20 parts by weight of an inorganic filler.
