    Abstract: Water soluble polymers are prepared by the process of reacting a first monomer selected from the group consisting of maleic acid, maleic anhydride and alkali metal salts of maleic acid with at least one other copolymerizable monomer in water in the presence of 18 - 40 parts by weight of persulfate catalyst per 100 parts by weight of monomer. The catalyst is preferably potassium persulfate. The resulting polymers are useful ingredients in detergent compositions, especially those used for machine dishwashing.

    Abstract translation: 水溶性聚合物通过以下方法制备：在18-40重量份的存在下使选自马来酸，马来酸酐和马来酸酐的马来酸酐和马来酸的碱金属盐的至少一种其它可共聚单体在水中反应的第一种单体 的过硫酸盐催化剂每100重量份的单体。 催化剂优选为过硫酸钾。 所得聚合物是洗涤剂组合物中的有用成分，特别是用于机器洗碗的那些。

    Abstract: The disclosed diaryl urethanes are made by capping poly(oxyalkylene) diols with monoisocyanates. These diurethanes are characterized by a desirable hydrophobe/hydrophile balance typically evidenced by low cloud points, the ability to form micelles in aqueous media, the ability to reduce stable foam, and the ability to be taken up and retained by paper fibers, thereby imparting increased hydrophilic character to paper sheets made from the fiber. The low foaming or de-foaming capability of these compounds is particularly useful in paper re-wet compositions and machine dishwashing detergents and additives. The hydrophobe/hydrophile balance is typically obtained through a combination of oxyethylene and oxypropylene units or blocks in the oxyalkylene chain.

    Abstract translation: 所公开的二芳基聚氨酯通过用单异氰酸酯封端聚（氧化烯）二醇来制备。 这些二氨基甲酸酯的特征在于通常由低浊点，在水性介质中形成胶束的能力，降低稳定的泡沫的能力以及由纸纤维吸收和保留的能力，从而赋予增加的所需的疏水物/亲水平衡 由纤维制成的纸张具有亲水性。 这些化合物的低发泡或脱泡能力在纸再湿组合物和机洗碗碟洗涤剂和添加剂中特别有用。 疏水物/亲水平衡通常通过在氧化烯链中的氧化乙烯和氧化丙烯单元或嵌段的组合来获得。
