  • Vinyl chloride-based copolymer and preparation method thereof
    Patent number: 11795249
    Abstract: Provided are a novel structure of a copolymer, a preparation method thereof, a vinyl chloride-based resin composition including the copolymer, and a coating ink including the vinyl chloride-based resin composition. According to the present invention, when the vinyl chloride-based resin composition including the copolymer is used, compatibility with ethylene vinyl acetate is excellent, and ink dispersibility and ink color are also excellent.
    Type: Grant
    Filed: July 24, 2019
    Date of Patent: October 24, 2023
    Assignee: HANWHA SOLUTIONS CORPORATION
    Inventors: Moon Soo Gil, Chul-Woong Lee, Hyeok Chil Kwon

  • PVC-based compound composition
    Patent number: 10208197
    Abstract: The present invention relates to a polyvinyl chloride (PVC)-based compound composition, and more specifically, to a PVC-based compound composition that uses a PVC-based copolymer having internal plasticity prepared by suspension polymerization together with a PVC resin, thereby increasing compatibility with the PVC resin to shorten the gelling time, lowering the load at the time of extrusion to increase production in the same process conditions, and partially showing an impact modifier substitution effect.
