Mixtures of fluoropolymers and oxidized polyarylene sulfides A polymer mixture of A) at least one fluoropolymer in a proportion of from 50 to 99% by weight and B) at least one polyarylene sulfone or polyarylene compound containing at least two of the bridges --S--, --SO-- and --SO.sub.2 -- or a mixture of the two in a proportion of from 1 to 50% by weight, where the sum of components A) and B) is always 100% by weight. This mixture is used for the production of sliding bearings or gasket materials having a reduced tendency to creep and reduced abrasion.
