Abstract: Compact polyurethane elastomer comprises 7-11 vol.% of magnetizable particles. An independent claim is included for a process for preparing the compact polyurethane elastomer, comprising producing the compact polyurethane elastomer in the presence of magnetic particles, so that the magnetic particles are present in the compact polyurethane elastomer.

Abstract: The present invention relates to aqueous polymer dispersions of polymers made of polymerized ethylenically unsaturated monomers M which comprise or consist of: a) 55 to 88% by weight, based on the total weight of the monomers M, of at least one monomer Ma consisting of a1) at least one monomer Ma(1) selected from alkyl acrylates having a branched alkyl radical having 3 to 20 carbon atoms, alkyl methacrylates having a branched alkyl radical having 5 to 20 carbon atoms, where the homopolymer of monomer Ma(1) has a theoretical glass transition temperature of at most 10°C and optionally a2) at least one monomer Ma(2) selected from alkyl acrylates having a linear alkyl radical of 2 to 6 carbon atoms; wherein the weight ratio of monomer Ma(2) to Ma(1) is at most 2:1; b) 8 to 30% by weight, based on the total weight of the monomers M, of a monomer Mb, which is a monoethylenically unsaturated carbonitrile; c) 0 to 25% by weight, based on the total weight of the monomers M, of at least one non-ionic monoethylenically unsaturated monomer Me which is different from the monomers Mb and whose homopolymer has a glass transition temperature of at least 60°C; provided that the total amount of monomer Mb and Me is in the range of 12 to 40% by weight, based on the total weight of the monomers M; d) at most 2.0% by weight, based on the total weight of the monomers M, of one or more monoethylenically unsaturated monomers Md having an acidic group; e) at most 5% by weight, based on the total weight of the monomers M, of at least one ethylenically unsaturated monomer Me which, alone or with a crosslinking agent, has crosslinking effect and which is different from the monomers Ma to Md; f) at most 10% by weight based on the total weight of the monomers M, of at least one non-ionic monoethylenically unsaturated monomer Mf which has a water- solubility of at least 100 g/L and which is different from the monomers Me; provided that the total amount of monomers Md, Me and Mf does not exceed 10% by weight, based on the total weight of the monomers M. The polymers are suitable as polymer adhesives, in particular as polymer adhesives or binders, respectively, in aqueous flooring adhesive compositions.

Abstract: The present invention relates to cellular elastomers, wherein the cellular elastomer comprises magnetizable particles, which have a chain-shaped orientation parallel to one another. In addition, the invention relates to a method for producing cellular elastomers, preferably cellular polyurethane elastomers, with cellular polyurethane elastomers having a density according to DIN EN ISO 845 between 200 kg/m 3 and 5000 kg/m 3 (wherein the weight of said magnetizable particles is taken into consideration) being particularly preferred. The cellular elastomers are produced in the presence of magnetizable particles such that said magnetizable particles are present in the cellular elastomer. The production of the cellular elastomers is carried out in the presence of a preferably artificial magnetic field, which has a flux density of greater than 0.01 tesla, preferably a flux density of between 0.05 and 2 tesla. In addition, the present invention relates to cellular elastomers obtained in this way, particularly shoe soles comprising the inventive cellular elastomers.
