A polymer mixture, which is characterized in that the mixture comprises the following two components: (A) 50 to 99 wt% of not less than one fluoro-containing polymer, however the polymer being not an elastomer; and (B) 1 to 50 wt% of not less than one poly(aryl sulfone) or oxidized poly(aryl thioether) or a mixture of the two polymers, in which the total amount of components (A) and (B) is 100 wt%, and in which: the component (A) comprises one of the re-solidifying units of the formulae (I) to (VIII): (I) (II) (III) (IV) (V) (VI) (VII) (VIII) in which, in the formula (I), X is O-R, and R is polyfluorinated C1-C8 alkyl, and in the formulae (I) to (IV), m and n each is a value between 0.01 to 1, and in which the sum of m and n is equal to 1; the component (B) comprises a polyaryl compound with re-solidifying units of the formula (X): (X) in which, there is no relevance between each E and it can be sec-phenyl, sec-naphthyl or biphenylylene, there is no relevance between b and c and its value is from 0 to 1, and
