    Abstract: Process for the preparation of homopolymers or copolymers by homopolymerization or copolymerization of free-radically polymerizable water-soluble and/or water-dispersible monomers, optionally with further comonomers and optionally with at least one crosslinker, in an inverse emulsion polymerization in the presence of at least one redox initiator pair comprising an oxidizing agent and a reducing agent, where the reducing agent is 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof; homopolymers or copolymers preparable by the process according to the invention, water-in-oil emulsions which comprise at least one homopolymer or copolymer according to the invention, solid compositions which comprise at least one homopolymer or copolymer according to the invention, the use of 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof as reducing agent in a process for the preparation of homopolymers or copolymers; the use of the water-in-oil emulsion comprising at least one homopolymer or copolymer according to the invention for the thickening of aqueous solutions, and the use of 2-hydroxy-2-sulfinatoacetic acid and/or salt thereof as reducing component of a redox initiator pair comprising an oxidizing agent and a reducing agent for avoiding induction times during inverse emulsion polymerization.

    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.
