Abstract:
A multilayer composite comprising a layer configuration A/C/B or A/C/B/C/A, whereinI. each layer A comprises a molding composition that comprises at least 50% by weight of a polymer A containing amino groups selected from the group consisting of polyamides, aminated polyolefins, poly(ether ester amide)s or poly (ether amide)s; II. layer B comprises a molding composition that consists of at least 50% by weight of a polymer B selected from the group consisting of thermoplastic polyester or fluoropolymer; III. each layer C comprises a molding composition that consists essentially of the following components a)-c): a) from 5 to 95 parts by weight of the polymer A, b) from 95 to 5 parts by weight of the polymer B, where the sum of the components a) and b) is 100 parts by weight, plus c) from 1 to 90 parts by weight of a compatibilizer comprising an alkyl acrylate polymer.
