Disclosed is a process for making aqueous polyacrylate dispersions having improved rheological and stability characteristics by the emulsion polymerization of acrylic esters and methacrylic esters in the absence of a protective colloid, comprising conducting the polymerization in the presence of, by weight of the total monomer content, from about 0.1 to 2% of at least one substantially completely water-soluble monomer having conjugated unsaturation. The resultant aqueous polyacrylate dispersions are useful in the manufacture of latex paints, binders for nonwoven materials, water-based inks, paper coatings and water-borne adhesives, such as pressure-sensitive adhesives.
公开了一种在没有保护胶体的情况下,通过丙烯酸酯和甲基丙烯酸酯的乳液聚合,制造具有更好的流变性和稳定性特征的聚丙烯酸酯水性分散体的工艺,包括在存在至少一种具有共轭不饱和度的基本上完全水溶性的单体(按单体总含量的重量计)约 0.1%至 2%的情况下进行聚合。 所得到的聚丙烯酸酯水性分散体可用于制造乳胶漆、无纺布材料的粘合剂、水基油墨、纸张涂料和水性粘合剂(如压敏粘合剂)。
