Patent number: 8669344Abstract: A method of removing a residual catalyst metal compound from a polymer solution 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.Type: GrantFiled: April 6, 2007Date of Patent: March 11, 2014Assignee: LG Chem, Ltd.Inventors: Hye-Young Jung, Sung-Ho Chun, Sung-Don Hong, Jung-Min Lee, Heon Kim, Dmitry Kravchuk

Patent number: 8329841Abstract: The present invention relates to a photoreactive polymer that comprises a multi-cyclic compound in a main chain, and a polymerization method thereof. Since the photoreactive polymer according to the present invention comprises a multi-cyclic compound having a high glass transition temperature as a main chain, the thermal stability is excellent, and since the mobility of the main chain is relatively high as compared to that of an additional polymer, a photoreactive group can be freely moved in the main chain of the polymer. Accordingly, it is possible to overcome a slow photoreactive rate that is considered a disadvantage of a polymer material used to prepare an alignment film for known liquid crystal display devices.Type: GrantFiled: December 15, 2011Date of Patent: December 11, 2012Assignee: LG Chem, Ltd.Inventors: Dai-Seung Choi, Hye-Young Jung, Sung-Ho Chun, Heon Kim, Sung-Don Hong, Dong-Woo Yoo
