Abstract: The present invention is a composition comprising a stable aqueous dispersion of polymer particles comprising structural units of a nonionic monoethylenically unsaturated monomer; 2-(methacryloyloxy)ethyl phosphonic acid (MEP) or a salt thereof; and a sulfur acid monomer or carboxylic acid monomer or a combination thereof or a salt thereof, as well as a composite comprising the polymer particles adsorbed to the surface of a pigment particle such as TiO2. The composition and composite are prepared using the phosphorus acid monomer MEP, which can be prepared in high purity with low residual non-polymerizable phosphorus acid, thereby reducing the load of neutralizing agent required to achieve the targeted pH as compared with phophoethyl methacrylate (PEM).
Abstract translation: 本发明是一种组合物，其包含稳定的包含非离子单烯属不饱和单体的结构单元的聚合物颗粒的水分散体; 2-（甲基丙烯酰氧基）乙基膦酸（MEP）或其盐; 和硫酸单体或羧酸单体或其组合或其盐，以及包含吸附在颜料颗粒如TiO 2表面上的聚合物颗粒的复合物。 使用磷酸单体MEP制备组合物和复合材料，其可以用低残留的非可聚合磷酸制备高纯度，从而降低与甲基丙烯酸磷酸乙酯（PEM）相比达到目标pH所需的中和剂的负载量， 。

Abstract: The present invention relates to a composition comprising an aqueous dispersion of acrylate-siloxane copolymer particles comprising structural units of an acrylate monomer; an acid monomer; and a siloxane acrylate monomer of formula I: where R, R1, R2, Y and x are as defined herein. The composition has a high solids content, a low concentration of siloxane acrylate monomer and low coagulum levels. The composition is useful for forming coatings with improved hydrophobicity, stain resistance, and aesthetic/haptic properties compared with conventional all-acrylic compositions.
