Abstract (en)
[origin: WO2014124774A1] The invention relates to a foamable bead polymer consisting of (meth)acrylonitrile, (meth)acrylic acid, copolymerizable latent expanding agents and optionally (meth)acrylic acid esters, to the production of said polymer by means of suspension polymerization and to the use thereof for producing foams. Using a bead polymer of this type it is possible, for example, to carry out a simple in-mould foaming process to produce products directly in the form of the desired workpiece. These workpieces are particularly suitable for use as components in spacecraft, aircraft, water and land craft and for other construction elements.
