Abstract: A process for producing aqueous solutions of acrylic acid polymers by polymerization of acrylic acid in feed operation with a free-radical starter in the presence of hypophosphite in water as solvent, which comprises (i) initially charging water and optionally acrylic acid in acidic, unneutralized form, optionally one or more ethylenicaliy unsaturated comonomers, optionally aqueous hypophosphite solution and optionally initiator, (ii) adding acrylic acid in acidic, unneutralized form, optionally one or more ethylenicaliy unsaturated comonomers, aqueous free-radical starter solution and aqueous hypophosphite solution, (iii) adding a base to the aqueous solution after termination of the acrylic acid feed, wherein the comonomer content does not exceed 30 wt % based on the total monomer content, wherein the acrylic acid, the aqueous free-radical starter solution and the aqueous hypophosphite solution are added such that the molar ratio x of acrylic acid to phosphorus-bound hydrogen [AA]/[P—H] over a time period in which at least 75% of the acrylic acid is converted has a value x which is constant to within ±0.5 and is in the range from 0.8 to 2.

Abstract: The present invention relates to a copolymer obtainable by copolymerization of
(A) at least one unsaturated dicarboxylic acid or derivatives thereof,
(B) at least one α-olefin having from at least 6 up to and including 20 carbon atoms,
(C) optionally at least one C3- to C20-alkyl ester of acrylic acid or methacrylic acid or a mixture of such alkyl esters and
(D) optionally one or more further copolymerizable monomers other than monomers (A), (B) and (C),
with a molar incorporation ratio of (A):(B):(C):(D) of 1:0.5 to 2.0:0 to less than 0.5:0 to 0.1
followed by the reaction with at least one dialkylamine (E), where the two alkyl radicals in the at least one dialkylamine (E) are independently alkyl radicals having at least 17 up to 30 carbon atoms.
