Polymer composition (C) containing (i) a poly(aryl ether sulfone) material (M12) composed of a poly(biphenyl ether sulfone) (P1) and, optionally in addition, a poly(aryl ether sulfone) (P2) containing recurring units with arylene groups linked to each other via a secondary, ternary or quaternary carbon atom, and (ii) a per(halo)fluoropolymer material (M34), composed of a per(halo)fluoropolymer (P3) of which at least 2.0 wt. % of the recurring units are derived from a per(halo)fluoromonomer other than tetrafluoroethylene, and a polytetrafluoro ethylene (P4). Shaped article, especially aircraft interior component, comprising the polymer composition (C).

Linvention concerne une composition polymère (C) contenant (i) un matériau poly(aryl éther sulfone) (M12) composé dun poly(diphényle éther sulfone) (P1) et, éventuellement en plus, un poly(aryle éther sulfone) (P2) contenant des unités récurrentes avec des groupes arylènes liés les uns aux autres via un atome de carbone secondaire, tertiaire ou quaternaire, et (ii) un matériau per(halo)fluoropolymère (M34), composé dun per(halo)fluoropolymère (P3) dont au moins 2,0 % en poids des unité récurrentes sont dérivées dun per(halo)fluoromonomère autre que le tétrafluoroéthylène, et un polytétrafluoroéthylène (P4). Linvention concerne en outre un article formé, notamment un composant intérieur daéronef, contenant la composition polymère (C).
