Patent number: RE45219Abstract: Provided are a photoreactive polymer that includes a multi-cyclicmulticyclic compound at as its main chain and a method of preparing the same. The photoreactive polymer exhibits excellent thermal stability since it includes a multi-cyclicmulticyclic compound having a high glass transition temperature at as its main chain. In addition, the photoreactive polymer has a relatively large vacancy so that a photoreactive group can move relatively freely in the main chain therein. As a result, a slow photoreaction rate, which is a disadvantage of a conventional polymer material used to form an alignment layer for a liquid crystal display device, can be overcome.Type: GrantFiled: September 14, 2012Date of Patent: October 28, 2014Assignee: LG Chem, Ltd.Inventors: Heon Kim, Sung Ho Chun, Keon Woo Lee, Sung Joon Oh, Kyungjun Kim, Jungho Jo, Byung Hyun Lee, Min Young Lim, Hye Won Jeong
