Abstract
A polyacetal resin composition having excellent friction resistance and abrasion resistance performances is provided by improving the compatibility, dispersibility and interfacial adhesiveness between the polyacetal resin and an olefinic polymer. To a polyacetal resin (A), 1 to 100 parts by weight based on 100 parts by weight of the resin (A) of a modified olefinic polymer (B) modified with at least one member selected from the group consisting of an unsaturated carboxylic acid and an acid anhydride thereof, and their derivatives, and 0.1 to 100% by weight based on component (B) of an alkylene glycol polyme (C)r having a primary or secondary amino group(s) and having a number-average molecular weight of 400 to 500,000 are blended.
