    • Process for the preparation of an aqueous styrene/butadiene polymer dispersion by free radical aqueous emulsion polymerization of a monomer mixture M comprising from 30 to 80% by weightof styrene, from 20 to 70% by weightof butadiene and from 0 to 40% by weightof at least one ethylenically unsaturated comonomer differing from styrene and butadiene, based in each case on the total amount of the monomer mixture I, by a monomer feed process in the presence of a noncopolymerizable hydroperoxide of the general formula R—O—O—H as a regulator, in which the monomer mixture M is fed to the polymerization vessel in the course of 4 hours.
    • 通过单体混合物M的自由基水乳液聚合制备苯乙烯/丁二烯聚合物水分散体的方法,包括
      从苯乙烯的30〜80重量% 从丁苯和 从20至70重量% 至少一种烯属不饱和 与苯乙烯不同的共聚单体 和丁二烯 基于单体混合物I的总量,通过单体进料方法在通式为ROOH的不可共聚氢过氧化物作为调节剂存在下,在 在4小时内将单体混合物M加入到聚合容器中。
