Abstract: A process for the preparation of random radical copolymers which comprises a) at least one olefinically unsaturated sulfonic acid of the formula (I), where n is 0 to 10; X is 0 or NR5; R1 is hydrogen or methyl; R2, R3 independently of one another are hydrogen or C1- to C6-alkyl and R5 is hydrogen, alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, aryloxyalkyl, alkoxyaryl, hydroxyalkyl, (di)alkylaminoalkyl, (di)alkylaminoaryl, (di)arylaminoalkyl, alkylarylaminoalkyl or alkylarylaminoaryl, it being possible for the aryl radicals to be monosubstituted or polysubstituted, salts thereof or mixtures of acid and salts and b) at least two structurally different olefinically unsaturated monomers of the formula (II), where Y is O or NR7; R5 is hydrogen or methyl; R6 is alkyl, hydroxyalkyl, (di)alkylaminoalkyl or (di)alkylaminoaryl and R7 is hydrogen, alkyl, aryl, alkylaryl, arylalkyl, alkoxyalkyl, aryloxyalkyl, alkoxyaryl, hydroxyalkyl, (di)alkylaminoalkyl, (di)alkylaminoaryl, (di)arylaminoal
