PLASTIC COMPOSITE ELEMENT AND PROCESS FOR PRODUCTION AND USE THEREOF

PROBLEM TO BE SOLVED: To provide a composite element which, owing to excellent mechanical properties, can be used such as in car construction and in which an adhesion between a plastic and a polyisocyanate polyaddition product adhering thereto is not lost even during long-term storage at 80°C and 80...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a composite element which, owing to excellent mechanical properties, can be used such as in car construction and in which an adhesion between a plastic and a polyisocyanate polyaddition product adhering thereto is not lost even during long-term storage at 80°C and 80% relative humidity. SOLUTION: A prepolymer containing isocyanate groups produced by reacting at least one isocyanate and one polycarbonate polyalcohol with a functionality of 2 to 3 and a hydroxyl number of 40 to 400 mg KOH/g, based on the condensation of carbonates with a diol and/or a triol with a molecular weight of 62 to 3,000 g/mol, and having the isocyanate group content of 5 to 48%. The composite element containing a thermoplastic polymer layer adhering to a layer comprising the reaction product of a mixture containing a compound reactive with isocyanate.
