    摘要: A tribologically modified polyoxymethylene polymer composition is disclosed. The polyoxymethylene polymer composition is comprised of a polyoxymethylene polymer, reinforcing fibers, and at least one tribological modifier. The tribological modifier may comprise at least one tribological modifier comprising an ultra-high molecular weight silicone having a kinematic viscosity of greater than about 100,000 mm2s−1. The composition may exhibit a dynamic coefficient of friction against a counter-material of from about 0.001 to about 0.2. The polyoxymethylene polymer compositions provide polymer articles with improved tribological properties and mechanical properties. In one embodiment, the composition contains a polyoxymethylene polymer having functional groups, a coupling agent, reinforcing fibers, and the above silicone.
