Beschreibung
Zusammenfassung:	The invention relates to a process for producing a foam moulding from poly(meth)acrylimide, an adhesion promoter or an adhesion promoter mixture and optionally assistants, comprising the following steps: - grinding a polymer moulding composed of poly(meth)acrylimide, - coating the ground material obtained in the preceding step with an adhesion promoter, - introducing the coated ground material into a mould, - optionally adding the assistants, - heating the mould, - cooling the mould at foaming temperature - demoulding the foam moulding. The resulting foam moulding has outstanding mechanical properties and is suitable, inter alia, as a component for production of space, air, water and land vehicles.
