| 20110009529 | Copolymer Having Polyether Side Chains And Dicarboxylic Acid Derivative Components - The invention relates to a copolymer which can be used as a superplasticizer for hydraulic binders and comprises 30 to 47 mol % of a (meth)allyl alcohol polyether derivative structural unit and 53 to 70 mol % of a maleic acid derivative structural unit. | 01-13-2011 |
| 20110034592 | Aqueous Solution Containing Copolymers with Polyether Side Chains - The invention relates to a process for the preparation of an aqueous solution comprising 30 to 95% by weight of water and 5 to 70% by weight of a copolymer dissolved in the water by free radical solution polymerizations of an isoprenol polyether derivative with an acrylic acid derivative, so that the copolymer has 20 to 45 mol % of an isoprenol polyether derivative structural unit and 55 to 80 mol % of an acrylic acid derivative structural unit. The aqueous solution is suitable as a superplasticizer for hydraulic binders. | 02-10-2011 |
| 20110054083 | Copolymer Comprising Polyether Side Chains and Hydroxyalkyl and Acid Structural Units - The invention relates to a copolymer which is suitable as a superplasticizer for hydraulic binders and comprises 5 to 55 mol % of an isoprenol polyether derivative structural unit, 2 to 90 mol % of an acrylic acid derivative structural unit and 2 to 90 mol % of a hydroxyalkyl acrylate structural unit. | 03-03-2011 |
| 20110126421 | Method For Removing Water From A Mixture - The invention relates to a method for removing water from a mixture containing at least one compound having at least one group reactive towards isocyanate and containing water, the mixture being applied to the surface of a rotating body A, the mixture flowing over the surface of the rotating body A to an outer region of the surface of the rotating body A and water evaporating from the mixture. In particular, this method is suitable for removing water from alcohols and amines. | 06-02-2011 |
| 20110132144 | Method For Producing Metal Nanoparticles In Polyols - The invention relates to a process for the preparation of metal nanoparticles, selected from the group consisting of lead, bismuth, zinc, antimony, indium, gold, nickel, cobalt, palladium, platinum, iridium, osmium, rhodium, ruthenium, rhenium, vanadium, chromium, manganese, niobium, molybdenum, tungsten, tantalum, cadmium, silver and/or copper, on a rotating body, characterized in that a reduction of corresponding metal salts, corresponding metal salt complexes, corresponding metal hydroxides and/or corresponding metal oxides by polyols having a number of hydroxyl groups in the polyol of 1 to 10 and a molecular weight of the polyols of 2000 to 18 000 Da is effected. | 06-09-2011 |
| 20110132551 | Method For Removing Non-Reacted Isocyanate From Its Reaction Product - The present invention relates to a method for removing isocyanate from a reaction product of isocyanate with compounds reactive towards isocyanates, the reaction product being applied to the surface of a rotating body A, the reaction product flowing over the surface of the rotating body A to an outer region of the surface of the rotating body A and isocyanate which was used for the preparation of the reaction product and has not reacted evaporating from the mixture in the process. | 06-09-2011 |
| 20110144288 | Production of Silylated Polyurethane and/or Polyurea - The invention relates to a process for the preparation of silylated polyurethanes and/or polyureas, comprising the steps: a) application of a component β) containing isocyanate and of a component α) containing polyol and/or polyamine to at least one surface of body A, which surface rotates about an axis of rotation and has a temperature between 60 and 400° C., and b) reaction of the reaction product of β) isocyanate and α) polyol and/or polyamine with a silylating agent. | 06-16-2011 |
