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 unsaturate d 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.

Abstract: The invention relates to a method for producing an aqueous styrene-butadiene polymer dispersion by the radical aqueous emulsion-polymerisation of a monomer mixture M, containing: between 40 and 80 wt. % styrene as monomer M1; between 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 atoms, 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 hydrocarbon KW is already present in the polymerisation vessel and the residual quantity of the hydrocarbon KW is fed to the polymerisation reaction during the course of the latter.
