    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing an aqueous solution of a copolymer, wherein the time of occupation of a reactor for producing an aqueous solution of a copolymer can be shortened by avoiding or reducing foaming. SOLUTION: In producing an aqueous solution of a copolymer comprising (a) 50-99.5 mass% of at least one ethylenically unsaturated monocarboxylic acid and/or dicarboxylic acid (monomer A), (b) 0.5-50 mass% of at least one ethylenically unsaturated compound (monomer B) selected from an ester of an amine having at least one hydroxy group with an ethylenically unsaturated monocarboxylic acid, and a monoester and diester of the amine with an ethylenically unsaturated dicarboxylic acid, and (c) up to 20 mass% of at least one other monomer (monomer C), the monomers A, B and C are polymerized in an aqueous medium in the presence of at least one foam inhibitor.

    Abstract: The invention relates to a method for producing alkylpolyalkylene glycol esters of monoethylenically unsaturated carboxylic acids by esterifying (a) monoethylenically unsaturated carboxylic acids with (b) polyalkylene glycols which are closed on one side by terminal groups, in a substance in the presence of polymerisation inhibitors and esterification catalysts at temperatures of 160 DEG C at the most. The esterification is first carried out at atmospheric pressure or at pressures of up to 50 bar, the water produced during the esterification is then distilled from the reaction mixture at a pressure of between 10 and 500 mbar, and the esterification is then continued at atmospheric pressure or at pressures of up to 50 bar.
