Definitions

  • This invention relates to ester functionalization of vinyl terminated polyolefins by metathesis reactions.
  • Metathesis is generally thought of as the interchange of radicals between two compounds during a chemical reaction.
  • metathesis reactions such as ring opening metathesis, acyclic diene metathesis, ring closing metathesis, and cross metathesis. These reactions, however, have had limited success with the metathesis of functionalized olefins.
  • Methods for the production of polyolefins with end-functionalized groups are typically multi-step processes that often create unwanted by-products and waste of reactants and energy.
  • End-functionalized multiblock polyolefins that feature a chemically reactive or polar end group are of interest for use in a broad range of applications, such as compatibilizers, tie-layer modifiers, surfactants, and surface modifiers.
  • the instant invention's use of olefin alkene metathesis to introduce functional groups is both a commercially economical and an "atom-economical" route to end functionalized multiblock polyolefins.
  • This invention further provides vinyl-terminated polyolefins that react with functionalized alkenes in the presence of a metathesis catalyst to form polar end-functionalized multiblock polyolefins.
  • a novel method for polar end functionalized multiblock polyolefin production by the metathesis of vinyl- terminated polyolefins with ester functionalized alkenes is useful in a range of polyolefins, including isotactic polypropylene (iPP), atactic polypropylene (aPP), ethylene propylene copolymer (EP), and polyethylene (PE).
