Herberts Gesellschaft mit beschrankter Haftung Abstract The description relates to liquid polymer preparations with non-Newtonian flow properties, methods of producing them and coating agents containing them and suitable more particularly for multi-layer decorative lacquer coats. The liquid polymer preparations are made from a) an aqueous dispersion having a viscosity of 20 - 200 mPa.s and containing one or more dispersed polymers obtained by suspension or emulsion polymerisation of 2 - 10 wt.% acrylonitrile and/or methacrylonitrile 1 - 3 wt.% acrylamide and/or methacrylamide and 87 - 97 wt.% of one or more acrylic acid ester and/or methacrylic acid ester monomers, by b) adding a non water-miscible solvent which dissolves or swells the polymers, in a proportion such that the viscosity increases to at least 104 times the original viscosity and c) simultaneously or subsequently adding a diluent miscible with water and with the dissolving or swelling solvent until the viscosity is 25 - 1000 mPa.s, after which d) water is optionally removed.
