    Abstract: New active agent formulations contain active agent(s) (A); random radical copolymer(s) (B), derived from sulfoalkyl (meth)acrylate or N-sulfoalkyl-(meth)acrylamide monomer(s) (I) (and/or their salts), (meth)acrylate ester or N-substituted (meth)acrylamide monomer(s) (II) and optionally further monomers; and optionally further additives (C). New active agent formulations contain active agent(s) (A); random radical copolymer(s) (B), derived from olefinically unsaturated sulfonic acid(s) of formula (I) (and/or their salts), monomer(s) of formula H 2C=C(R 4>)-CO-YR 6> (II) and optionally further monomers; and optionally further additives (C). n : 0-10; X, Y : O or NR 5>; R 1>, R 4>H or Me; R 2>, R 3>H or 1-6C alkyl; R 5>, R 6>H, alkyl, aryl, alkylaryl, alkoxyalkyl, aryloxyalkyl, alkoxyaryl, hydroxyalkyl, (di)alkylaminoalkyl, (di)arylaminoalkyl, alkylarylaminoalkyl or alkylarylaminoaryl (where aryl groups are optionally substituted). Independent claims are included for: (1) the preparation of aqueous dispersions, by contacting the formulations with aqueous systems (optionally in presence of additives) and dispersion conventionally; (2) the preparation of the formulations, by dissolving (A) - (C) and optionally further additives in an organic solvent (or dissolving the components separately in organic solvents then mixing the solutions), then conventionally removing the solvent; and (3) an alternative preparation of the formulations, by forming an aqueous solution of (B); dissolving (A), (C) (if present) and optionally further additives in water-miscible organic solvent(s); mixing the solutions; applying energy to form a dispersion; and conventionally removing the solvent.
