Silylenes and Germylenes for Catalysis of Olefin Polymerization


Robert West, Daniel Moser, Michael Havey

The Wisconsin Alumni Research Foundation (WARF) is seeking commercial partners interested in developing a method of using divalent silicon and germanium compounds to catalyze olefin polymerization reactions.
OVERVIEWTypically, a catalyst is required to polymerize olefins.  However, current catalysts are inefficient, complex and expensive.
THE INVENTIONUW-Madison researchers have developed a method of using divalent silicon and germanium compounds to catalyze olefin polymerization reactions.  Specifically, the method uses a cyclic silylene or cyclic germylene in the presence of terminal alkene or alkyne monomers as a catalyst to synthesize olefin polymers.
  • Olefin polymerization
  • Catalysis reactions will run effectively at a silylene or germylene concentration of 4 percent and perhaps even lower concentrations.
  • Silylene molecules can polymerize ethylene, propylene, butylene, as well as heavier alkene monomers.
  • Silylene and germylene catalysts are much more efficient, less complex, relatively easy to make and less expensive than currently used catalysts.
