A method for controlling the thickening of aqueous systems comprising silicates, which comprises adding to the aqueous system at least one copolymer of a mean molecular weight Mw of at least 3000 g/mol to at most 60 000 g/mol and the copolymer being made up essentially randomly from monoethylenically unsaturated monocarboxylic acids, monoethylenically unsaturated dicarboxylic acids and other ethylenically unsaturated comonomers, the polymerization for producing the copolymer being performed in the presence of from 0.01 to 100 mol % of at least one base, based on the total amount of all COOH groups of the monocarboxylic and dicarboxylic acids, the quantitative figures in % by weight being respectively based on the total amount of all monomers used.

Control of the thickening of silicate-containing aqueous systems

Use of copolymers comprising alkylene oxide units, which copolymers comprise incorporated randomly or blockwise by polymerization  as additive to phosphate- and/or phosphonate-comprising aqueous systems in industrial technical plants.

Use of copolymers containing alkylene oxide units as an additive to aqueous systems

A description is given of (meth)acrylic acid copolymers containing methacrylic acid units, the polymer being functionalized with aminoalkylsulfonic acid. In addition, a description is given of a process for preparation thereof and use thereof for water treatment, scale inhibition in petroleum production and corrosion inhibition in aqueous systems.
