Abstract: The invention relates to a method for controlling the thickening of aqueous, silicate-containing systems, characterized in that at least one copolymer having an average molecular weight (Mw) of at least 3000 g/mol and not more than 60000 g/mol is added to said aqueous system and that the copolymer is, essentially statistically, made of monoethylenically unsaturated monocarboxylic acids, monoethylenically unsaturated dicarboxylic acids and eventually ethylenically unsaturated comonomers. The method is also characterized in that the polymerization is carried out in the presence of 0.01 to 100 mol-%, in relation to the total amount of all COOH groups of the mono- and dicarboxylic acids, of at least one base for producing the copolymer, the indicated amounts in wt.-% each referring to the total amount of all used monomers.
