An epoxy resin composition [composition (C)] comprising: (i) from 30 to 90% by weight of at least one epoxy compound [compound E], based on the total weight of the composition (C); (ii) from 0 to 60% by weight of at least one curing agent [agent C], based on the total weight of the composition (C); (iii) from 0 to 15% by weight of at least one accelerator, based on the total weight of the composition (C); (iv) from 1 to 60% by weight of at least one poly(aryl ether sulfone) (I) [PAES (I-1)], based on the total weight of the composition (C) and wherein said PAES (I-1) polymer comprises amine functional groups in an amount equal to or more than 200 &#x3bc;eq/g; (v) from 1 to 60% by weight of at least one poly(aryl ether sulfone) (I) [PAES (I-2)], based on the total weight of the composition (C), and wherein said PAES (I-2) polymer is different from the PAES (I-1) polymer.

Epoxy resin compositions

Flexible pipe (fP) suitable for transporting hydrocarbons, said flexible pipe comprising at least one polymer layer (L) composed of a polymer composition (C) comprising at least one poly(aryl ether ketone) (P1), and at least one per(halo)fluoropolymer (P2). The poly(aryl ether ketone) (P1) and the per(halo)fluoropolymer (P2) are advantageously homogeneously distributed in the polymer composition (C). The polymer composition (C) is profitably prepared by a method comprising tumble blending the per(halo)fluoropolymer (P2) on one hand, and the poly(aryl ether ketone) (P1) or part of the poly(aryl ether ketone) (P1) on the other hand.
