| abstract |
A composite material having improved thermal and mechanical properties is provided by a thermoplastic multilayer composite consisting at least of (I) a layer of a polyvinylidene fluoride moulding composition, (II) a layer directly adjacent to the layer I, comprising a moulding composition based on a mixture of (a) from 40 to 90% by weight of a polyamide, and (b) from 10 to 60% by weight of a polyglutarimide, (III) a layer directly adjacent to the layer II comprising a suitable coupling agent, and (IV) a layer directly adjacent to the layer III, comprising a polyolefin moulding composition, with adjacent layers being firmly bonded to one another. By means of the invention it is possible to obtain composite materials having the desired improved property profile. |
