Abstract
The invention relates to novel thermoplastic multi-layer composites comprising at least a) a layer formed from a molding compound based on a polyamide and b) a second layer formed from a molding compound based on a linear alternating polyketone polymer from carbon monoxide and an ethylenically unsaturated hydrocarbon compound, at least part of which layer b) is adjacent to layer a).
Claims30
A thermoplastic multi-layer composite, the thermoplastic multi-layer composite comprising:
- a first layer that comprises a first moulding compound the first moulding compound based on a polyamide, the polyamide having a ratio of amino to carboxyl end groups greater than 1;
- and
- a second layer that comprises a second moulding compound, the second moulding compound based on a linear alternating polyketone, the linear alternating polyketone based on carbon monoxide and an ethylenically unsaturated hydrocarbon compound, at least part of the second layer located adjacent and adhesively bonded to at least part of the first layer.
