    Abstract: The present invention relates to a process for the synthesis of organosulfate salts of amino acid esters comprising the steps of reacting at least one lactam with at least 3 carbon atoms in the lactam ring with sulfuric acid in an aqueous solution followed by esterification of the reaction product of the previous step with at least 200 mol-% of at least one alcohol selected from the group consisting of linear alkyl alcohol containing one hydroxy group, branched alkyl alcohol containing one hydroxy group, linear alkylether alcohol containing one hydroxy group, branched alkylether alcohol containing one hydroxy group, phenoxyalkanols containing one hydroxy group, and mixtures thereof; followed optionally removal of water and/or removal of excess alcohol.

    Abstract: A copolymer which comprises, in copolymerized form, (A) 60 to 99% by weight of at least one monoethylenically unsaturated poly-alkylene oxide monomer of the formula I in which the variables have the following meanings: X is —CH2— or —CO—, if Y is —O—; is —CO—, if Y is —NH—; Y is —O— or —NH—; R1 is hydrogen or methyl; R2 are identical or different C2-C6-alkylene radicals, which may be arranged blockwise or randomly; R3 is hydrogen or C1-C4-alkyl; n is an integer from 25 to 75, (B) 1 to 40% by weight of at least one quaternized nitrogen-containing monoethylenically unsaturated monomer selected from the group consisting of monomers of formula IIa to IId in which the variables have the following meanings: R is C1-C4-alkyl or benzyl; R′ is hydrogen or methyl; Y is —O— or —NH—; A is C1-C6-alkylene; X— is halide, C1-C4-alkyl sulfate, C1-C4-alkylsulfonate and C1-C4-alkyl carbonate, (C) 0 to 10% by weight of anionic monoethylenically unsaturated monomers, and (D) 0 to 30% by weight of other nonionic monoethylenically unsaturated monomers and has an average molecular weight Mw of >100,000.
