More Information
Summary:The invention relates to a method for controlling the thickening of aqueous systems containing silicates, characterized in that at least one copolymer having an average molecular weight Mw of more than 60000 g/mol is added to said aqueous system and that the copolymer consists, essentially statistically, of monoethylenically unsaturated monocarboxylic acids, monoethylenically unsaturated dicarboxylic acids and, optionally, other ethylenically unsaturated comonomers, the indicated amounts referring to the total amount of all used monomers, respectively.
