    Abstract: A process for preparing an aqueous styrene-butadiene polymer dispersion by free-radical aqueous emulsion polymerization of a monomer mixture M containing from 40 to 80% by weight of styrene as monomer M1, from 20 to 60% by weight of butadiene as monomer M2, and from 0 to 40% by weight, based on 100% by weight of monomers, of ethylenically unsaturated comonomers M3 other than styrene and butadiene by a monomer feed technique in the presence of from 0.05 to 0.5% by weight, based on 100% by weight of monomers, of at least one hydrocarbon HC having 6 to 20 carbon atoms, which is selected from compounds which on abstraction of a hydrogen atom form a pentadienyl radical or a 1-phenylallyl radical and from alpha-methylstyrene dimer comprises including at least 30% of the hydrocarbon HC in the initial charge to the polymerization vessel and supplying the remainder of the hydrocarbon HC to the polymerization reaction in the course of that 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 the concentration of the butadiene in the monomer feed is increased by at least 10 wt. % in relation to the monomers in the feed process, for a period of at least 1 % of the entire feed duration, when at least 70 % of the monomers to be polymerised have been fed to the polymerisation reaction.
