Laminate comprising a polyester type protective layer

摘要

Multi-layer composite (I) comprises an internal layer (1) (fluoropolymer molding material and polyolefin molding material), an adhesion mediator layer (2) and a layer of a polyester molding material (3), where (2) exhibits 2-80 wt.parts of a grafting copolymer. Multi-layer composite (I) comprises an internal layer (fluoropolymer molding material and polyolefin molding material), an adhesion mediator layer and a layer of a polyester molding material, where the adhesion mediator layer exhibits 2-80 wt.parts of a grafting copolymer (which is obtained by the monomers: 0.5-25 wt.% of grafting copolymer, polyamine with at least 4 nitrogen atoms and monomers forming polyamide such as lactams, omega -aminocarboxylic acids and/or equimolar combination of diamine and dicarboxylic acid; 0-85 wt.parts of a polyester; 0-85 wt.parts of polymers such as polyamides, fluoropolymers and polyolefins, where the sum of the wt.parts of the monomers results to 100; and maximum 50 wt.parts of additives such as impact resisting rubber and/or usual auxiliary and/or additional materials).
