Mixtures of fluoropolymers and oxidized polyarylene sulfides

A copolymer mixture which consists 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 different bridges selected from the group consisting of --S--, --SO-- and --SO.sub.2 -- in a proportion of from 1 to 50% by weight
• where the sum of components A) and B) is always 100% by weight.

A polymer mixture which consists essentially of

• A) at least one fluoropolymer in a proportion of from 70 to 99% by weight and
• B) at least one polyarylene sulfone or polyarylene compound containing at least one of the bridges --SO-- or --SO.sub.2 -- or a mixture of the two in a proportion of from 1 to 30% by weight,
• where the sum of components A) and B) is always 100% by weight and said polymer mixture has a sulfone content of at least 65%.
