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: 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.
