    • The invention relates to aqueous active ingredient compositions in which the active ingredient or ingredients are present in the form of an aqueous dispersion of finely divided polymer-active ingredient particles which comprise at least one water-insoluble polymer P, at least one surface-active substance, and at least one organic active crop protection ingredient which is present in the polymer particles and has a solubility in water of not more than 5 g/l at 25° C./101.325 hPa, in which the polymer-active ingredient particles have an average particle diameter, determined by dynamic light scattering, in the range from 300 to 1200 nm, preferably in the range from 310 to 1000 nm, and more particularly in the range from 320 to 800 nm, the polymer P being a polymer of ethylenically unsaturated monomers M which comprise 0.1% to 10%, more particularly 0.2% to 7%, and especially 0.3% to 5%, by weight, based on the total amount of the constituent monomers M of the polymer P, of at least one monoethylenically unsaturated compound M2 which is selected from monoethylenically unsaturated sulfonic acids, monoethylenically unsaturated phosphonic acids, and monoethylenically unsaturated phosphoric monoesters, and also the salts thereof, the amounts in % by weight being based on the acid form of the monomer M2.The invention also relates to a process for preparing them and to the use of active ingredient compositions of this kind.
    • 本发明涉及水性活性成分组合物,其中活性成分或成分以细分散的聚合物 - 活性成分颗粒的水分散体的形式存在,其包含至少一种水不溶性聚合物P,至少一种表面活性物质 ,以及存在于聚合物颗粒中并且在25℃/ 101.325hPa下在水中的溶解度不超过5g / l的至少一种有机活性作物保护成分,其中聚合物 - 活性成分颗粒具有 通过动态光散射确定的平均粒径在300至1200nm的范围内,优选在310至1000nm范围内,更特别地在320至800nm的范围内,聚合物P是烯属不饱和聚合物 基于聚合物P的构成单体M的总量,包含0.1重量%至10重量%,更特别为0.2重量%至7重量%,特别是0.3重量%至5重量%的单体M为至少1微米 选自单烯属不饱和磺酸,单烯属不饱和膦酸和单烯属不饱和膦酸单酯的烯属不饱和化合物M2及其盐,其量以单体M2的酸形式为基准。 本发明还涉及其制备方法和使用这种活性成分组合物。
