Patent ID: 8865281

Claim:
A flexible pipe, said flexible pipe comprising several layers arranged in a modular construction wherein at least some of the layers are independent and un-bonded from each other, at least one of said layers being a polymer layer (L) comprising a polymer composition (C) comprising: at least one poly(aryl ether ketone) (P1), at least one per(halo)fluoropolymer (P2), and optionally at least one polyarylene (P3), and optionally at least one poly(aryl ether sulfone) (P4), wherein the total weight of the poly(aryl ether ketone) (P1), based on the total weight of the poly(aryl ether ketone) (P1) and the per(halo)fluoropolymer (P2), is above 65% and of at most 99%, wherein a total weight of the per(halo)fluoropolymer (P2), based on a total weight of the polymer composition (C), is above 1% and below 30%, wherein, if the polyarylene (P3) is present, the total weight of the poly(aryl ether ketone) (P1), based on the total weight of the polymer composition (C), is above 50%, wherein, if the poly(aryl ether sulfone) (P4) is present, the total weight of the poly(aryl ether sulfone) (P4) over the total weight of the poly(aryl ether ketone) (P1) ratio is below 1, and wherein the poly(aryl ether ketone) (P1) has a content of more than 50 wt % of recurring units of any of formulae (I) through (V): wherein each Ar is independently phenylene, biphenylene, or naphthylene, each X is independently O, C(═O), or a direct bond, n is an integer of from 0 to 3, b, c, d, and e are 0 or 1, and a is an integer of from 1 to 4.
