摘要： The invention relates to a method for producing aqueous solutions of acrylic acid polymers by polymerizing acrylic acid in feed mode with a radical starter in the presence of hypophosphite in water as a solvent, wherein (i) water and optionally acrylic acid in acidic, non-neutralized form, optionally one or more ethylenically unsaturated comonomers, optionally aqueous hypophosphite solution, and optionally initiator are introduced, (ii) acrylic acid in acidic, non-neutralized form, optionally one or more ethylenically unsaturated comonomers, aqueous radical starter solution, and aqueous hypophosphite solution are added, (iii) after the end of the acrylic acid feed, a base is added to the aqueous solution, wherein the comonomer content does not exceed 30 wt% with respect to the total monomer content, characterized in that the acrylic acid, the aqueous radical starter solution, and the aqueous hypophosphite solution are added in such a way that, over a time period in which at least 75% of the acrylic acid is converted, the molar ratio x of acrylic acid to phosphorus-bonded hydrogen [AA]/[P-H] has a value x that is constant to ±0.5 and that lies in the range of 0.8 to 2.

摘要： The invention relates to a method for producing water soluble polymers of esters from ethylenically unsaturated carboxylic acids and polyalkylene glycols by azeotropic esterification of ethylenically unsaturated carboxylic acids with polyalkylenglycols which are closed at one side by end groups. Esterification is performed in the presence of organic solvents which together with water form an azeotrope of at least 85 weight %. Subsequent radical polymerization is performed on the esters thus obtained thereby optionally together with other ethylenically unsaturated monomers in an aqueous medium. The organic solvent is azeotropically strip distilled out of the reaction mixture during the polymerization process and strip distilled water is reintroduced or the amount of water strip distilled out of the reaction mixture is replaced by adding fresh water.
