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