Abstract: The invention relates to a method for producing random radical copolymers, characterized by the following steps: a) dissolving by heating a) at least one olefinically unsaturated sulfonic acid of formula (I); wherein n is 0 to 10; X represents O or NR; R represents hydrogen or methyl; R, R independently represent hydrogen or C to C alkyl and R represents hydrogen, alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, aryloxyalkyl, alkoxyaryl, hydroxyalkyl, (di)alkylaminoalkyl, (di)alkylaminoaryl, (di)arylaminoalkyl, alkylarylaminoalkyl or alkylarylaminoaryl, wherein the aryl groups can be mono- or polysubstituted, the salts thereof or mixtures of acid and salts and b) at least two structurally distinct olefinically unsaturated monomers of formula (II), wherein Y represents O or NR; R represents hydrogen or methyl; R represents alkyl, hydroxyalkyl, (di)alkylaminoalkyl or (di)alkylaminoaryl and R represents hydrogen, alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, aryloxyalkyl, alkoxyaryl, hydroxyalkyl, (di)alkylaminoalkyl, (di)alkylaminoaryl, (di)arylaminoalkyl, alkylarylaminoalkyl or alkylarylaminoaryl, and c) optionally one or more olefinically unsaturated monomers which can be structurally distinct from components (a) and (b), and at least one initiator, either (i) in a solvent mixture which contains water and a solvent having a boiling point below 140°C and being soluble in water, or (ii) in one or more pure alcohols, and polymerizing said mixture in solution, the copolymer formed also remaining dissolved. The copolymers obtainable according to the above method are suitable as formulation adjuvants in agrochemical active ingredient compositions.
