  • Cycloolefin-based polymer compound, preparation method thereof and selective hydrogenation process
    Patent number: 8735521
    Abstract: 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: Grant
    Filed: February 11, 2009
    Date of Patent: May 27, 2014
    Assignee: Kolon Industries, Inc.
    Inventors: Ik Kyung Sung, Woon Sung Hwang, Jung Hoon Seo, Bun Yeoul Lee, Sung Jae Na, Seung Taek Yu
