Polymeric supported catalysts
This invention relates to a catalyst system comprising a substituted, bridged bisindenyl metallocene supported on a polymeric support wherein the metallocene is activated for polymerization by an ionizing reaction and stabilized in cationic form with a noncoordinating anion. A protonated ammonium sa...

| description | This invention relates to a catalyst system comprising a substituted, bridged bisindenyl metallocene supported on a polymeric support wherein the metallocene is activated for polymerization by an ionizing reaction and stabilized in cationic form with a noncoordinating anion. A protonated ammonium salt of a noncoordinating amine is covalently bonded to the support. Propylene polymers produced by these supported catalyst systems have melting points and polymer microstructures similar to propylene polymers produced using analogous unsupported catalyst systems. |
