Chromium catalyst compositions and ethylene polymerization processes therewith |
| abstract |
This invention provides a chromium catalyst system that comprises [a] a support that comprises silica, wherein said support has a surface area to pore volume relationship as follows0.5</=Pore volume</=f(SA) wherein said f(SA) is(1.14x10-7)(SA)3-(1.19x10-4)(SA)2+(3.19x10-2)(SA)+0.20;and [b] a hexavalent chromium compound; wherein the surface concentration of said hexavalent chromium on said support is from 0.25 to 1 hexavalent chromium atoms per square nanometer. Another embodiment of this invention provides a process to homopolymerize ethylene, or copolymerize ethylene with a comonomer, said process comprises polymerizing ethylene with the above chromium catalyst composition. |
