Abstract
Polymer mixtures comprising at least one thermoset and at least one oxidized polyarylene sulfide have particularly good tribological behavior. Oxidized polyarylene sulfides used in these mixtures are polyarylene sulfones or oxidized polyarylene sulfides in which at least 10% of the sulfur bridges have been converted to sulfone bridges. Polyphenylene sulfone is employed with preference. The polymer mixtures are used to produce gearwheels, gear racks, bearings, chains, wheels or gasket materials.
