Abstract
The invention relates to a polymer composition containing 3 to 90% by weight of a copolymer H and 3 to 90% 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, at least 60 mol % of the polyether macromonomer structural units of the copolymer H being represented by the isoprenol polyether derivative structural units and at least 60 mol % of the polyether macromonomer structural units of the copolymer K being represented by the vinyloxy polyether derivative structural units.
