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 NR5 R1 represents hydrogen or methyl R2, R3 independently represent hydrogen or C1 to C6 alkyl and R5 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 NR7 R5 represents hydrogen or methyl R6 represents alkyl, hydroxyalkyl, (di)alkylaminoalkyl or (di)alkylammoaryl and R7 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.
