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 carrying out a radical aqueous emulsion polymerization of a monomer mixture M containing: 40 to 80 wt. % of styrene depicted as Monomer M1; 20 to 60 wt. % of butadiene depicted as monomer M2, and; 0 to 40 wt. %, with regard to 100 wt. % of the monomers, of ethylenically unsaturated comonomers M3 that differ from styrene and butadiene. The polymerization is carried out according to a monomer feeding method in the presence of 0.05 to 0.5 wt. %, with regard to 100 wt. % of the monomers, of at least one hydrocarbon KW selected among compounds having 6 to 20 C atoms that form a pentadienyl radical or a 1-phenylallyl radical when a hydrogen atom is abstracted, and the .alpha.-methylstyrene dimer. The inventive method is characterized in that the monomers to be polymerized are introduced within three hours of the polymerization reaction.
