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.

Abstract: The present invention relates to a polymer dispersion comprising A) at least one first phase comprising a) at least one chain growth addition polymer P constructed from 1 to 99.9 wt % of at least one ester from ethylenically unsaturated monomers, as monomer A, 0 to 20 wt % of at least one ethylenically unsaturated carbonitrile, as monomer B, 0.1 to 5 wt % of at least one acid-functional ethylenically unsaturated monomer, as monomer C, 0 to 5 wt % of at least one monomer which, alone or with a crosslinking agent, has crosslinking effect and which is different from the monomers A to C, as monomer D, 0 to 20 wt % of at least one ethylenically unsaturated monomer which forms a chain growth addition homopolymer having a glass transition temperature 50° C.

Abstract: The invention relates to a cellular elastomer which is anisotropic, with anisotropy being defined by the compressive modulus in one of three orthogonal directions being greater than that in the other two directions by a factor of at least 1.5. The invention also relates to a cellular elastomer containing magnetizable particles which have a chain-like alignment along one spatial direction. The invention also relates to a process for producing a cellular elastomer containing magnetiable particles and the use of such elastomers in articles of manufacture.
