Beschreibung
Zusammenfassung:	The invention describes a method for producing a foam moulding from poly(meth)acrylimide, an adhesion promoter or an adhesion promoter mixture and optional auxiliaries, comprising the following steps: grinding a polymeric moulding made of poly(meth)acrylamide, coating the grindings obtained in the preceding step with an adhesion promoter, introducing the coated grindings into a mould, optionally adding the auxiliaries, heating the mould, cooling the mould below the foaming temperature, and demoulding the foam moulding. The resulting foam moulding has outstanding mechanical properties and is suitable for applications including as a component in the production of space, air, water and land vehicles.
