) selected from the group consisting of (i) mixes of at least one poly(aryl ether ketone) (P2′
) and at least one poly(aryl ether sulfone) (P3′
), and (ii) mixes of at least one poly(aryl ether ketone) (P2′
), at least one poly(aryl ether sulfone) (P3′
) and at least one fluoropolymer (P4′
),wherein; more than 50 wt. % of the recurring units of the polyarylene (P1′
) are recurring units (R1′
) of one or more formulae consisting of an optionally substituted arylene group, provided said optionally substituted arylene group is linked by each of its two ends to two other optionally substituted arylene groups via a direct C—
C linkage,the poly(aryl ether ketone) (P2′
) is a polycondensate, of which more than 50 wt. % of the recurring units are recurring units (R2′
) of one or more formulae containing at least one arylene group, at least one ether group (—
O—
