Systems and methods for Atom Transfer Radical Polymerization (ATRP) emulsion polymerization are provided. The ATRP emulsion polymerization comprises a suspending medium, a dispersed medium, a surfactant, a transition metal compound in a higher oxidation state, a ligand, and an ATRP initiator. The transition metal compound is capable of forming a catalyst complex in a presence of the ligand. The catalyst complex is soluble in the suspending medium and is capable of forming an ionic complex with the surfactant. The ionic complex is capable of moving between the suspending medium and the dispersed medium. A portion of the transition metal compound in the higher oxidation state within a portion of the catalyst complex is reduced by a physical and/or a chemical procedure thereby initiating a polymerization of one or more radically (co)polymerizable monomers by reaction with the initiator.

Aqueous binder compositions for binding fibers comprise a vinyl acetate-ethylene copolymer of 60 to 94% by weight vinyl acetate, 5 to 30% by weight ethylene and 0 to 20% by weight of further ethylenically unsaturated comonomers copolymerizable therewith, polymerized in the presence of polyvinyl alcohol in aqueous medium, wherein the polymerization is carried out in the presence of a copolymer B) containing 20 to 50% by weight of monomer units derived from ethylenically unsaturated carboxamides, 20 to 50% by weight of monomer units derived from ethylenically unsaturated monocarboxylic acids, and 20 to 50% by weight of monomer units derived from ethylenically unsaturated dicarboxylic acids or anhydrides thereof.

The invention relates to a synergistically active composition which comprises a mixture of a sulfinic acid or a salt thereof and ascorbic acid or a salt thereof and the use of the composition as reducing agent. The reducing power of the composition of the invention is significantly higher than the reducing power of the single components.
