  • Patent number: 9260599
    Abstract: 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.

  • Publication number: 20150361236
    Abstract: The invention relates to a foamable bead polymer consisting of (meth)acrylonitrile, (meth)acrylic acid, copolymerizable latent blowing agents and optionally (meth)acrylic esters, the preparation thereof by suspension polymerization and the use thereof for producing foams. Such a bead polymer makes it possible, for example, to carry out in-mould foaming in a simple way and thus produce products having the shape of the desired workpiece directly. These workpieces are highly suitable as components in space, air, water and land vehicles and for other construction elements.
