Definitions

  • Melamine-formaldehyde precondensates i) may be unmodified, but they may also be modified, for example up to 20 mol% of the melamine may be replaced by other thermoset agents known per se, for example alkyl-substituted melamine, urea, urethane, carboxamides, dicyandiamide, guanidine, Sulfuryl amide, sulfonic acid amides, aliphatic amines, phenol and phenol derivatives.
  • other thermoset agents known per se, for example alkyl-substituted melamine, urea, urethane, carboxamides, dicyandiamide, guanidine, Sulfuryl amide, sulfonic acid amides, aliphatic amines, phenol and phenol derivatives.
  • the elastic material preferably contains the magnetizable particles in the form of a dispersion.
  • magnetizable particles it is possible to use all known magnetizable particles. In such particles, a magnetic dipole moment is induced in an external magnetic field which enhances the effect of the external magnetic field. These may also have their own magnetic field in a space free from external magnetic fields, but the own magnetic field is amplified by an external magnetic field.
  • Ferro- or ferrimagnetics more preferably soft magnetic ferro- or ferrimagnetics, are preferably used. Such particles are described, for example, in WO 2006/007882, US Pat. No. 6,476,113 B1, US 2005/0116194 A1 or WO 2006/024457 A1.
  • the preparation is carried out by impregnation with the solution of the elastic material
  • solvents such as water, ethanol, acetone, tetrahydrofuran, ethyl acetate and butyl acetate can be used.
  • the solvent is selected so that it can dissolve or disperse the elastic material and a film formation of the dissolved polymer at temperatures below 100 0 C allows, but does not damage the elastic foam, for example by dissolving or swelling of the elastic foam. It may be advantageous, if possible, to use water as a solvent in order to avoid the formation of flammable or harmful or environmentally harmful vapors.
