Abstract
The invention relates to a polymer composition containing 5 to 95% by weight of a copolymer H and 2 to 60% by weight of a copolymer K, the copolymers H and K each having polyether macromonomer structural units and acid monomer structural units, which are present in the copolymers H and K in each case in a molar ratio of 1:20 to 1:1, and at least 20 mol % of all structural units of the copolymer H and at least 25 mol % of all structural units of the copolymer K being present in each case in the form of acid monomer structural units, the polyether macromonomer structural units of the copolymer H having side chains containing in each case at least 5 ether oxygen atoms, the number of ether oxygen atoms per side chain of the polyether macromonomer structural units of the copolymer H varying in such a way that the corresponding frequency distribution diagram, in which the number of ether oxygen atoms per side chain of a polyether macromonomer structural unit is plotted along the abscissa and the associated frequency for the copolymer H is plotted along the ordinate, contains at least 2 maxima.
