  • Modified copolymer of olefin and cycloolefin
    Patent number: 6667379
    Abstract: The present invention provides an olefin/cycloolefin/alkylstyrene copolymer which is non-functionalized, functionalized, or grafted. By the functionalization of the benzylic protons of the alkylstyrene unit, the copolymer can be functionalized. The functionalized or grafted olefin/cycloolefin/alkylstyrene copolymer has good adhesion to a substrate and good compatibility with other polymers compared with the non-functionalized copolymer.
    Type: Grant
    Filed: December 28, 2001
    Date of Patent: December 23, 2003
    Assignee: Industrial Technology Research Institute
    Inventors: Shu-Hua Chan, Chi-Lan Li, Ching Ting, Joung-Yei Frank Chen
