  • Patent number: 6335404
    Abstract: The present invention provides an efficient aqueous polymerization process for preparing a water soluble polymer product having a molecular weight of less than 30,000. The polymer product is formed from about 3 to about 50 weight percent of at least one monoethylenically unsaturated dicarboxylic acid monomer, from about 50 to about 97 weight percent of at least one monoethylenically unsaturated monocarboxylic acid monomer, and from 0 to about 40 weight percent of one or more carboxyl-free monoethylenically unsaturated monomers. The process of the present invention may be run as a batch or continuous process. The process uses at least one chain transfer agent and is conducted at an aqueous solution pH of about 3 or less to keep the molecular weight of the polymer product below 30,000. The polymer product produced by the process of the present invention is useful as an additive in detergents, cleaning formulations, and water circulating systems.

  • Patent number: 5858944
    Abstract: Polycarboxylate additives suitable for use in automatic dishwasher detergent compositions are prepared by polymerizing three or more monomers including monoethylenically unsaturated C.sub.3 to C.sub.6 monocarboxylic acids such as acrylic acid, monoethylenically unsaturated C.sub.4 to C.sub.6 dicarboxylic acids such as maleic acid, and monoethylenically unsaturated esters of acrylic or methacrylic acid. Automatic dishwasher detergents prepared from these additives produce low filming and spotting on washed glassware.
