    Abstract: The invention relates to a method for producing an aqueous styrene-butadiene polymer dispersion by means of radical aqueous emulsion polymerisation of a monomer mixture M containing styrene, butadiene, and optionally up to 30 wt. %, in relation to 100 wt. % of monomers, of ethylenically unsaturated comonomers other than styrene and butadiene. The reaction is carried out in a polymerisation vessel according to a monomer supply method, in the presence of a regulator system comprising, in relation to 100 wt. % of monomers, between 0.02 and 0.5 wt. % of at least one hydrocarbon KW having between 6 and 20 C atoms and being selected from compounds forming a pentadienyl radical or a 1-phenylallyl radical by means of abstraction of a hydrocarbon atom, an .alpha.-methylstyrene dimer, and between 0.3 and 2 wt. % of an organic compound S with at least one SH group. The inventive method is characterised in that at least 30 %, preferably at least 50 %, especially at least 80 %, and ideally the entire amount (or more than 95 %) of the hydrocarbon KW is present in the polymerisation vessel.

    Abstract: The invention relates to a method for producing an aqueous styrene-butadiene polymer dispersion by the radical aqueous emulsion-polymerisation of a monom er mixture M, containing: between 40 and 80 wt. % styrene as monomer M1; betwee n 20 and 60 wt. % butadiene as monomer M2 and between 0 and 40 wt. %, (in relation to l00 wt. % monomers), of ethylenically unsaturated comonomers M3 that differ from styrene and butadiene, according to a monomer feed process in the presence of between 0.05 and 0.5 wt. %, (in relation to l00 wt. % monomers), of at least one hydrocarbon KW comprising between 6 and 20 C atom s, selected from compounds, which form a pentadienyl or a 1-phenylallyl radical during the abstraction of a hydrogen atom, or from .alpha.-methylstyrene dimers. Said method is characterised in that at least 30 % of the hydrocarbo n KW is already present in the polymerisation vessel and the residual quantity of the hydrocarbon KW is fed to the polymerisation reaction during the cours e of the latter.

    Abstract: The invention relates to a method of selectively hydrogenating ethylenically unsaturated double bonds in polymers (P) by reacting an aqueous dispersion of at least one polymer (P) with hydrogen in the presence of at least one hydrogenation catalyst that comprises at least one transition metal, selected from rhodium and/or ruthenium, and at least one anionic, phosphorous compound that can form a coordinative bond with a transition metal. The inventive method is further characterized by integrating the hydrogenation catalyst into the aqueous dispersion of the polymer (P) without adding a solvent. The invention also relates to the aqueous dispersions of the hydrated polymers (P) obtained according to the inventive method and to coating agents that contain such dispersions.

    Abstract: Graft rubbers comprising a graft core and a graft sheath are prepared by selective hydrogenation of ethylenically unsaturated double bonds of the elastomeric rubber polymer graft core with hydrogen in the presence of a catalyst comprising salts and complex compounds of rhodium and/or ruthenium whereby the aqueous rubber polymer dispersion contains upto 20 vol. % of an organic solvent. Graft rubbers (I) comprising a graft core and a graft sheath are prepared by: (A) preparation of an aqueous dispersion of at least one elastomeric rubber polymer prepared from at least one conjugated diene, optionally at least one copolymerizable monomer, optionally at least one modifying monomer; (B) followed by selective hydrogenation of ethylenically unsaturated double bonds of the elastomeric rubber polymer with hydrogen in the presence of a catalyst comprising salts and complex compounds of rhodium and/or ruthenium whereby the aqueous dispersion of the rubber polymer contains upto 20 vol. % of an organic solvent to prepare the graft core; and (C) grafting at least one graft shell onto the graft core prepared from at least one styrene compound of formula (1), optionally at least one monoethylenically unsaturated nitrile compound and optionally at least further monomer.
