  • High adhesive acrylate monomer and method for preparing the same
    Patent number: 8404885
    Abstract: A high adhesive acrylate monomer has a specific chemistry figure. This monomer may be easily prepared in a simplified way, and various linkers may be used between L-DOPA and an acrylate group attached to a tail of L-DOPA, so molecular weight and size of the entire material may be easily controlled. Also, various kinds of acrylate to be combined to a isocyanate compound used as a linker may be selected, so various molecules may be easily composed.
    Type: Grant
    Filed: December 3, 2008
    Date of Patent: March 26, 2013
    Assignee: LG Chem, Ltd.
    Inventors: Woo-Sung Kim, Jee-Seon Kim, Ja-Young Han
  • UV curable photochromic composition and products formed by using the same
    Patent number: 8137595
    Abstract: The present invention relates to a UV curable photochromic composition comprising a photochromic dye and an acrylate-based prepolymer having a polyol structure in which an acrylate-based functional group is introduced by using an iso-cyanate-based compound having two or more isocyanate functional groups as a linker, and to products formed by using the same.
