PREPARATION OF AQUEOUS STYRENE-BUTADIENE POLYMER DISPERSIONS

摘要

A process for preparing an aqueous styrene-butadiene polymer dispersion by free-radical aqueous emulsion polymerization of a monomer mixture M comprising - styrene, - butadiene, and if desired - up to 30% by weight, per 100% by weight of monomers, of ethylenically unsaturated comonomers other than styrene and butadiene; by a monomer feed technique, said process comprising supplying to the polymerization reaction in the course thereof a regulator system comprising, based on 100% by weight of monomers, - from 0.02 to 0.4% by weight of terpinolene and - from 0.5 to 2% by weight of an organic compound S containing at least one SH group.
