Patent number: 8735521Abstract: A cycloolefin-based copolymer and a hydrogenation process are disclosed, wherein the cycloolefin-based copolymer is prepared by using: a monomer which can be easily and economically obtained by hydrogenating dicyclopentadiene that occupies much of C5 fractions from naphtha cracking; or a monomer which can be obtained by chemically bonding three molecules of cyclopentadiene via Diels-Alder reactions and then hydrogenating the cyclopentadiene. The copolymer can be used in various fields as an amorphous transparent resin.Type: GrantFiled: February 11, 2009Date of Patent: May 27, 2014Assignee: Kolon Industries, Inc.Inventors: Ik Kyung Sung, Woon Sung Hwang, Jung Hoon Seo, Bun Yeoul Lee, Sung Jae Na, Seung Taek Yu

Publication number: 20140128558Abstract: The present disclosure relates to the field of solar cells. An amine-containing difluoro benzotriazolyl polymer, preparation method, and use thereof are provided; the polymer has a structure as represented by formula (I), both R1 and R2 are alkyls from C1 to C20, n is an integer from 10 to 50. In the polymer of the present disclosure, because the 1, 2, 3-benzotriazole solar cell material contains two fluorine atoms, the HOMO energy level is reduced by 0.11 eV, the fluorine-substituted 1, 2, 3-benzotriazole has two imido groups with strong electron-withdrawing property; the 1, 2, 3-benzotriazole is a heterocyclic compound with strong electron-withdrawing property, and an alkyl chain can be easily introduced to the N-position of the N—H bond of the benzotriazole; the functional group of the alkyl chain can improve solar energy conversion efficiency, thus solving the low efficiency problem of the solar cell made from the solar cell material.Type: ApplicationFiled: September 23, 2011Publication date: May 8, 2014Applicant: Ocean's King Lighting Science & Technology Co., LtdInventors: Mingjie Zhou, Ping Wang, Zhenhua Zhang, Hui Huang
