  • Dispersion-type acrylic copolymer
    Patent number: 9902792
    Abstract: This dispersion-type acrylic copolymer has a matrix (I) formed of an acrylic copolymer having a glass transition temperature of 50° C. or higher and a polymer unit (II) formed of an acrylic copolymer having a glass transition temperature of less than 50° C., the polymer unit (II) forms localized regions having an average diameter of 5-300 nm in the matrix (I), the matrix (I) and polymer unit (II) contain units of a crosslinking component, and the content of these units of a crosslinking component is more than 2% by mass relative to the total weight of the acrylic copolymer.
    Type: Grant
    Filed: August 20, 2014
    Date of Patent: February 27, 2018
    Assignee: Mitsubishi Chemical Corporation
    Inventors: Saori Kikuchi, Eiko Okamoto, Hiroshi Niino
  • Radically polymerizable polyether, method for producing said radically polymerizable polyether, polymerizable composition comprising said radically polymerizable polyether and radically polymerizable vinyl monomer, and copolymer, molded article and film each formed by radical polymerization of said polymerizable composition
    Patent number: 9718919
    Abstract: Provided is (1) a radically polymerizable polyether which imparts excellent mechanical properties including excellent transparency, a high degree of elongation at break and high bending strength to a copolymer produced by the radical polymerization of a radically polymerizable monomer, and a method for producing the radically polymerizable polyether; (2) a polymerizable composition comprising the radically polymerizable polyether and a radically polymerizable vinyl monomer, which enables the formation of a copolymer having excellent mechanical properties; and (3) a copolymer, a molded article and a film, each of which comprises the copolymer.
