Abstract: Flatting agents for coatings obtained by reacting a polyolefin wax (A) with a vinyl aromatic compound (B) and a copolymerizable Alpha , Beta -olefinically unsaturated dicarboxylic anhydride (C), optionally partially replaced by at least one Alpha , Beta -olefinically unsaturated monocaraboxylic acid, the molar ratio of (B) to (C) being from 0.7:1 to 1:0.7 and the sum of the weights of (B) and (C) being from 2 to 50 percent by weight of the weight of polyolefin wax (A). The reaction is carried out at temperatures of from 100* to 200*C, in the presence or absence of conventional free-radical polymerization initiators. The agents are particularly suitable for coatings containing organic solvents.
