Abstract

A composition comprises a polyoxymethylene having an inherent viscosity in p-chlorophenol (0.5% solution) of at least 1.0 and a reaction rate constant for thermal degradation at 222 DEG C. of less than 1% by weight of polymer per minute, and 0.1 to 4% by weight of a pulverulent metallic powder uniformly dispersed therein. The metal powder may be aluminium, copper, nickel, or an alloy of these metals, or silver or gold. The polyoxymethylene may have a number average molecular weight of at least 15,000. Specifications 753,299 and 770,717 are referred to.
