Abstract: An aqueous polymer dispersion obtained by first polymerising, in a first polymerisation step by the free-radical, aqueous emulsion polymerisation method, a monomer composition 1 and subsequently, in a polymerisation step 2, a monomer composition 2 in the presence of the product mixture from polymerisation step 1, where one of the two monomer compositions essentially comprises hard monomers and the other monomer composition essentially comprises soft monomers, and where, in addition to the monomer compositions 1 and 2, nitrogen-containing adhesion monomers are copolymerised, of which at least 20 mol % of the total amount of the adhesion monomers are copolymerised in polymerisation step 1.

Abstract: The thickening agent (thickener) for physically drying paints and coatings which contain binders which are soluble in white spirit is a copolymer which forms a gel in white spirit and contains (a) from 7 to 15% by weight of acrylates and/or methacrylates of monoalkanols having 8 carbon atoms, (b) from 0.05 to 0.2% by weight of a crosslinking agent, (c) from 25 to 35% by weight of styrene and (d) from 49.8 to 67.95% by weight of at least one acrylate and/or methacrylate of monoalkanols having 4 carbon atoms, in copolymerised form, with the proviso that the total of the % by weight for (a) to (d) is always 100. The thickener is prepared by emulsion polymerisation of the parent monomers in the presence of alkylsulphonates as emulsifier.
