Patent ID: 8586673

Claim:
A polymer composition (C), comprising: more than 75 wt. % and below 98 wt. %, based on the total weight of the polymer composition (C), of a poly(aryl ether sulfone) material (M12) consisting of at least one poly(biphenyl ether sulfone) (P1), and and 0.1 to 5 wt. %, based on the total weight of the polymer composition (C), of a per(halo)fluoropolymer material (M34) consisting of: 55 to 75 wt. %, based on the total weight of the per(halo)fluoropolymer material (M34), of at least one per(halo)fluoropolymer (P3) of which at least 2.0 wt. % of the recurring units are recurring units (R3) derived from at least one per(halo)fluoromonomer other than tetrafluoroethylene, and 45 to 25 wt. %, based on the total weight of the per(halo)fluoropolymer material (M34), of at least one polytetrafluoroethylene (P4).
