摘要：
Y zeolites with different aluminium contents obtained by dealumination with ammonium hexafluorosilicate were evaluated as supports for bis(cyclopentadienyl)-zirconium dichloride catalysts. The activities of the supported and homogeneous systems were compared for ethylene polymerization. The most active heterogeneous catalyst was the one supported on the zeolite with the higher Si/Al ratio and external area.
