| 20090281264 | Method of Deashing From Polymer Solutions - Disclosed is a method of removing a residual catalyst metal compound from a polymer solution. The method comprises the steps of: a) mixing a solution in which at least one organic nitrogen compound is dissolved in a polar solvent and the polymer solution to precipitate a chelate compound of the organic nitrogen compounds and the residual catalyst metal compound, b) adding the polar solvent to the solution mixture to dissolve a chelate compound and to precipitate a polymer, and c) filtering the precipitated polymer. After the polymer polymerization is completed, an organic nitrogen compound solution is added to perform a chelate reaction with the residual catalyst metal compound in a solution phase, and the polar solvent is added to precipitate the polymer so that only polymer precipitates are filtered while an additional filtration process in respect to the chelate compound is not performed to easily remove the residual catalyst metal compound. Thereby, it is possible to produce products that are of good quality. | 11-12-2009 |
| 20100076166 | CYCLIC OLEFINS COMPOUNDS, POLYMERS COMPRISING THE SAME AND LIQUID CRYSTAL ALIGNMENT FILMS INCLUDING THE POLYMERS - The present invention relates to a novel cyclic olefin compound, a polymer including the cyclic olefin compound, a liquid crystal alignment film including the polymer, and a liquid crystal display device including the liquid crystal alignment film. Since the polymer includes the cyclic olefin compound as a main chain, the thermal stability is excellent and the photoreactive speed is high. Accordingly, the production time can be reduced, the production cost can be reduced, and the anchoring force of the liquid crystal can be increased because the alignment property is stabilized due to the curing. | 03-25-2010 |

| 20110119841 | FABRIC CLEANING - The invention provides a method of laundering fabric which uses a pourable liquid detergent composition comprising 10-40% wt of surfactant, essentially consisting of nonionic and/or anionic surfactant (typically less than 90% wt LAS and at least 10% wt of nonionic surfactant) in which 10-40% wt of surfactant preferably passes the Calcium Tolerance Test described in the patent. The composition comprises no more than 15% wt of soap, (present as a minority in wt % terms of the total surfactant). In the method, the composition is diluted by a factor of greater than 500 to obtain a wash liquor which comprises 0.8-0.05 g/l of surfactant, and, the wash liquor is contacted with fabrics. The composition may further comprise one or more of and preferably combinations of lipase, polyethyleneimine, a blue violet dye, preferably with an optical adsorption peak in the range 540-600 nm, a fluorescer, a dye transfer inhibition polymer, a polycarboxylate anti-redeposition agent, a soil release polymer and a perfume (preferably encapsulated). | 05-26-2011 |
