  • Acrylic elastomer, acrylic elastomer composition, laminate, crosslinked product, and molded article
    Patent number: 9550842
    Abstract: Provided are an acrylic elastomer superior in adhesiveness to a fluorine-based elastomer, an acrylic elastomer composition containing the same, its laminate, and its crosslinked product and a molded article therefrom. Iodine groups are introduced as crosslinking groups into an acrylic elastomer to an iodine content of 0.1 to 2 mass % with respect to the total mass of the elastomer. In addition, 1 to 7 parts by mass of an organic peroxide and 1 to 5 parts by mass of an onium salt were blended with 100 parts by mass of the acrylic elastomer, to give an acrylic elastomer composition. Further, an acrylic elastomer layer of the acrylic elastomer composition is laminated with a fluorine-based elastomer layer of a fluorine-based elastomer composition mainly containing of a fluorine-based elastomer having iodine groups as crosslinking groups, to give a laminate. The laminate is then crosslinked to give a crosslinked product and a molded article.
