  • Multifunctional cyclobutarene peroxide polymerization initiators
    Patent number: 5087738
    Abstract: Multifunctional cyclobutarene peroxide polymerization initiators comprising at least one cyclobutarene moiety linked through the aromatic ring to at least one peroxide containing group which catalyze free radical polymerizations, as well as participate in cyclobutarene initiated ring opening polymerizations. The cyclobutarene peroxides of this invention are useful for the production of cross-linked, branched and graft polymeric compositions.
    Type: Grant
    Filed: May 22, 1991
    Date of Patent: February 11, 1992
    Assignee: The Dow Chemical Company
    Inventors: Wen H. Tong, Duane B. Priddy
  • Multifunctional cyclobutarene peroxide polymerization initiators
    Patent number: 5079322
    Abstract: Multifunctional cyclobutarene peroxide polymerization initiators comprising at least one cyclobutarene moiety linked through the aromatic ring to at least one peroxide containing group which catalyze free radical plymerizations, as well as participate in cyclobutarene initiated ring opening polymerizations. The cyclobutarene peroxides of this invention are useful for the production of cross-linked, branched and graft polymeric compositions.

  • Preparation of polymeric blend stock
    Patent number: 4822856
    Abstract: A process for preparing a polymeric blend stock comprising fluidizing a first particulated polymer, contacting the particulated polymer with droplets of a latex of a second polymer or polymer mixture, retaining the resulting product in a fluid state under conditions sufficient to dry the latex, and recovering the resulting dried polymeric blend stock.
