1. A multilayer polymer structure comprising a layer (A) comprising at least one fluorohydrocarbon polymer linked to a layer (C) comprising at least one olefin polymer via a layer (B) comprising from 97% to 10% by weight of at least one grafted olefin polymer and from 3 to 90% by weight of at least one fluorohydrocarbon polymer, wherein the grafted olefin polymer comprises units of at least one of a polymerizable monomer grafted onto a preactivated olefin polymer,
wherein the polymerizable monomer is at least one selected from the group consisting of alkyl acrylates, alkyl methacrylates, acrylamide, methacrylamide and fluorovinyl monomers.
