Patent application number | Description | Published |
20110237717 | Fine-particle, stable suspensions of functionalized, completely or partially hydrogenated nitrile rubbers - Novel stable aqueous suspensions of a functionalized, completely or partially hydrogenated nitrite rubber are provided with very low emulsifier content and small particle diameter, furtheron a process for production thereof and the use thereof for producing composite materials via coating of substrate materials with the suspension. | 09-29-2011 |
20120041126 | HNBR COMPOSITIONS WITH VERY HIGH FILLER LEVELS HAVING EXCELLENT PROCESSABILITY AND RESISTANCE TO AGGRESSIVE FLUIDS - The present invention relates to an elastomeric composition containing a nitrile rubber, preferably hydrogenated, and a filler. Compositions according to the present invention have high filler levels, excellent processability, and very good resistance to aggressive fluids and fuels compared to known HNBR compositions. | 02-16-2012 |
20130029069 | VULCANIZABLE POLYMER COMPOSITION COMPRISING A LOW MOLECULAR WEIGHT WITH OPTIONALLY HYDROGENATED NITRILE RUBBER - The present invention relates to vulcanizable polymer compositions comprising a very low molecular weight optionally hydrogenated nitrile rubber, at least one cross-linking agent, optionally at least one filler and optionally one or more further auxiliary products for rubbers, a process for preparing such vulcanizable polymer compositions, furtheron a process for vulcanizing such polymer compositions and the resulting vulcanizate, preferably as a shaped article. | 01-31-2013 |
20130211031 | PROCESS FOR THE PRODUCTION OF WATER AND SOLVENT-FREE NITRILE RUBBERS - The present invention relates to specific water and solvent-free nitrile rubbers having specific functional groups and/or end groups, a process for the production thereof and the use thereof. This process involves removing volatile compounds from a fluid (F) containing (1) at least one nitrile rubber and (2) at least one volatile compound, wherein the process comprises at least the steps of a.) treating the fluid (F) in at least one conversation unit, b.) retreating the concentrated fluid from step a.) in at least one retreating unit and c.) feeding the retreated concentrated fluid from step b.) into at least one retreating unit. | 08-15-2013 |
20130303700 | BLENDS OF PARTIALLY HYDROGENATED NITRILE RUBBER AND SILICONE RUBBER, VULCANIZABLE MIXTURES AND VULCANIZATES BASED THEREON - Novel rubber blends based on partly hydrogenated nitrile rubber and silicone rubber containing vinyl groups are provided, these being produced by a metathesis reaction in the presence of suitable catalysts, as are vulcanizable mixtures and vulcanizates based thereon, and the corresponding production processes. | 11-14-2013 |
20130331524 | HYDROGENATION OF DIENE-BASED POLYMERS - This invention relates to a process for the hydrogenation of diene-based copolymers in the presence of catalysts on specific carrier materials containing at least one hyper-branched polymer. | 12-12-2013 |
20140024784 | PROCESS FOR THE PRODUCTION OF WATER AND SOLVENT-FREE HYDROGENATED NITRILE RUBBERS - The present invention relates to a process for the production of water and solvent-free hydrogenated nitrile rubber polymers, to the hydrogenated nitrile rubbers and the use thereof. | 01-23-2014 |
