Patent ID: 8221890

Claim:
A multilayer composite comprising the following layers in order: I. an inner layer I selected from the group consisting of a fluoropolymer molding composition consisting of a fluoropolymer, a fluoropolymer molding composition consisting of a fluoropolymer and an electrically conductive additive, a polyolefin molding composition consisting of a polyolefin additive; and a polyolefin molding composition consisting of a polyolefin and an electrically conductive additive; II. a bonding layer II which has the following composition: a) from 2 to 80 parts by weight of a graft copolymer prepared from the following monomers: from 0.5 to 25% by weight, based on the graft copolymer, of a polyamine having at least 4 nitrogen atoms, and polyamide-forming monomers selected from the group consisting of lactams, ω-aminocarboxylic acids and equimolar combinations of diamine and dicarboxylic acid; b) from 0 to 85 parts by weight of a polyester, c) from 0 to 85 parts by weight of a polymer selected from the group consisting of polyamides, fluoropolymers and polyolefins, where the sum of the parts by weight of a), b) and c) is 100; d) not more than 50 parts by weight of one or more additives selected from the group consisting of impact-modifying rubber and customary auxiliaries and additives; a layer III of a polyester molding composition comprising a polyester and up to 40% by weight of another thermoplastic, wherein optionally, layer II or layer III or an additional inner layer additionally contains an electrically conductive additive.
