Structured particle latexes are prepared by emulsion polymerizing monomeric materials in aqueous media in one or more stages wherein in at least one of the stages a reactive polymeric surfactant is used. The resulting latex contains nonionic particles to which are bound the reactive polymeric surfactant which forms a layer containing stabilizing anionic or cationic groups such as sulfonic, sulfonium, quaternary ammonium, or sulfonate groups chemically bound at or near the surface of the polymer particles dispersed in the aqueous media. These latexes are particu- lady suitable for beater additives, coatings and composite binders.
结构颗粒胶乳是通过在
水性介质中乳化聚合单体材料的一个或多个阶段来制备的,其中至少有一个阶段使用了反应性聚合表面活性剂。生成的胶乳含有非离子粒子,这些粒子与反应性聚合物表面活性剂结合,形成一层含有稳定阴离子或阳离子基团(如
磺酸基、锍基、季
铵基或
磺酸基)的层,这些基团
化学结合在分散在
水介质中的聚合物粒子表面或其附近。这些胶乳尤其适用于打浆机添加剂、涂料和复合粘合剂。
