20120214941 | PROCESS FOR PREPARING AQUEOUS POLYACRYLIC ACID SOLUTIONS - A process for preparing aqueous solutions of homo- or copolymers of acrylic acid by means of free-radical polymerization of acrylic acid and optionally water-soluble, monoethylenically unsaturated comonomers in an aqueous medium in the presence of at least one water-soluble initiator and of at least one water-soluble regulator, wherein the polymerization is conducted by means of a continuous process, and wherein, after the polymerization, low molecular weight components are at least partly removed from the resulting aqueous polymer solution. For the polymerization, preference is given to using microstructured mixers and reactors. Preference is given to using at least one reactor and/or mixer with microstructures for the process. | 08-23-2012 |
20120322950 | BRANCHED POLYESTERS WITH SULFONATE GROUPS - Branched polyesters with sulfonate groups can be obtained by reacting components A, B, optionally C, and optionally D to yield branched polyesters, then reacting these branched polyesters with hydrogen sulfite. Component A is at least one α,β-olefinically unsaturated dicarboxylic acid, component B is at least one di- or higher-functional alcohol, optional component C is at least one di- or higher-functional carboxylic acid or hydroxycarboxylic acid without an α,β-olefinically unsaturated bond, and optional component D is at least one compound of formula CH | 12-20-2012 |
20130037491 | POLYMER MIXTURES AS DEPOSIT INHIBITORS IN WATER-BEARING SYSTEMS - A polymer mixture in solid or aqueous form includes a content of from 5 to 95% by weight of a first polymer and a content of from 5 to 95% by weight of a second polymer. The first polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 20 000 g/mol. The second polymer is a water-soluble or water-dispersible polymer having a weight-average molecular weight of 1000 to 50 000 g/mol. The polymer mixture can inhibit precipitation and sedimentation of calcium salts and magnesium salts in water-bearing systems. | 02-14-2013 |
