    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.
