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