Patent number: 8754179Abstract: The present discovery uses monomers which contain reversible photo-crosslinkable groups in addition to primary polymerizable groups. The mechanical properties of these materials and the reversibility of the photo-activated shape memory effect demonstrate the effectiveness of using photo-irradiation to effect change in modulus and shape memory effect. In the preferred embodiment the reaction mixture includes a photo-reactive monomer comprising a photo reactive group and a polymerizable group; a second monomer, which is more preferably a mixture of monomers, which are acrylate based; a multi-functional crosslinking agent, preferably 1,6 hexanediol diacrylate (HDODA); an initiator, preferably a free radical initiator; and a fifth, optional, component which is a modifying polymer. The mixture of the second monomer, crosslinking agent, and initiator comprise the base polymer matrix into which the photo-reactive monomer is incorporated.Type: GrantFiled: October 6, 2005Date of Patent: June 17, 2014Assignee: Cornerstone Research Group, Inc.Inventors: Tat Hung Tong, Emily Snyder

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
