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.
