  Aqueous coating compositions include an anionic species-scavenging system. The scavenging system includes an aqueous dispersion of water-insoluble, weak base-functional polymer particles. The particles are polymerized from monomer including a weak base-functional monomer such as 2-(diethylamino)ethyl methacrylate or 2-(t-butylamino)-ethyl methacrylate. A two stage process may be employed to prepare the particles and 2-(dimethylamino)-ethyl methacrylate may be included only in the initial stage. Alternatively, a single stage process may be employed using 2-(t-butylamino)methacrylate. The system also includes a volatile base such as ammonia to maintain the pH of the composition above the pKa of the weak base prior to and during application of the composition. As the volatile base is lost, the weak base is protonated and forms ion pairs with anionic species such as anionic surfactant. The compositions form coatings having good water resistance, and may be used as paints, paper coatings, caulking materials, adhesives, binders for non-woven products and for floor polishes and printing inks.

  水性涂料组合物包括阴离子物种清除系统。清除系统包括不溶于水的弱碱功能聚合物颗粒的水性分散体。这些微粒由单体聚合而成，单体包括弱碱官能团单体，如 2-(二乙基氨基)乙基甲基丙烯酸酯或 2-(叔丁基氨基)-乙基甲基丙烯酸酯。制备颗粒时可采用两阶段工艺，2-(二甲基氨基)-乙基甲基丙烯酸酯可仅用于初始阶段。另外，也可以使用 2-（叔丁氨基）甲基丙烯酸乙酯进行单阶段制备。该系统还包括挥发性碱（如氨），以便在使用组合物之前和使用期间将组合物的 pH 值保持在弱碱的 pKa 以上。随着挥发性碱的流失，弱碱被质子化，并与阴离子物质（如阴离子表面活性剂）形成离子对。这种组合物形成的涂料具有良好的耐水性，可用作油漆、纸张涂料、填缝剂、粘合剂、无纺布产品粘合剂以及地板抛光剂和印刷油墨。
• Surfactant inhibition of dental plaque

  The invention provides an oral preparation or composition such as a mouthwash, mouthrinse, toothpaste and the like containing certain classes of surfactants which act to inhibit plaque formation by inhibiting the initial adherence of bacteria to the dentin surfaces and in the case of one class of surfactants additionally inhibiting the glucosyl transferase catalysis to prevent the synthesis of extracellular polysaccharides from sucrose. The surfactants comprise substituted taurines, substituted isethionates and substituted hydroxy sultaines in which the substituents are long chain hydrocarbon radicals. The surfactants are employed in the aqueous-based oral compositions at concentrations between about 0.00001M to 0.1M to effect inhibition.

  本发明提供了一种口腔制剂或组合物，如漱口水、漱口液、牙膏等，其中含有某些类别的表面活性剂，这些表面活性剂通过抑制细菌在牙本质表面的初始附着来抑制牙菌斑的形成，其中一类表面活性剂还能抑制葡萄糖基转移酶的催化作用，从而防止蔗糖合成细胞外多糖。 这些表面活性剂包括取代的牛磺酸、取代的异硫酸盐和取代的羟基舒他命，其中的取代基是长链烃基。表面活性剂在水基口服组合物中的使用浓度约为 0.00001M 至 0.1M，以达到抑制效果。
