Abstract
Provided is a polyoxymethylene resin composition which comprises (I) 100 parts by weight of a polyoxymethylene polymer and (II) 1-200 parts by weight of a thermoplastic elastomer having a main dispersion peak temperature of −30° C. to +50° C. in a tan &dgr; curve obtained by the measurement of viscoelasticity and having a number average molecular weight of 10,000-500,000. Since moldings obtained from this resin composition simultaneously satisfy both the good frictional wear characteristics and the high vibration damping performances, they can be suitably employed for the uses such as vibration-proof sliding components in the fields of precision machines, OA appliances and automobiles.
