    Abstract: The thermoplastic composite material comprises a polyamide layer bonded to a polyester layer by means of an adhesive (I) comprising a blend of polyamide prepared from stoichiometric amounts of a diamine containing 6-12C atoms and dicarboxylic acids, and a polyester prepared from a diol containing a mixture of dicarboxylic acids. Thermoplastic composite material comprises a polyamide layer bonded to a polyester layer by means of an adhesive (I) comprising at least 50 wt.% of a blend of: (a) 20-80 wt.% of a polyamide prepared from stoichiometric amounts of a diamine containing 6-12C atoms and dicarboxylic acids, including at least 5 mol% of dicarboxylic acids (II) containing 10-36 C atoms; and (b) 20-80 wt.% of a polyester prepared from a diol containing 2-12 C atoms and a mixture of 30-95 mol% of an aromatic dicarboxylic acid containing 6-20 C atoms and 5-70 mol% (II). Independent claims are also included for the following: (1) production of the composite material by multicomponent injection molding, coextrusion or coextrusion/blow molding; (2) an adhesive as defined for (I).

    Abstract: 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).
