Abstract:
A supported catalyst comprising: a fluorided support composition having a fluorine concentration in the range of from 0.01 to 10.0 millimoles of fluorine per gram of support; a non-coordinating anion bound to the fluorided support composition; and a metallocene, wherein the supported catalyst is made by the process comprising:(a) contacting a support with a fluoriding agent at from 100Â° C. to 1000Â° C. to produce a fluorided support composition, wherein the support is selected from the group consisting of talc, clay, silica, alumina, magnesia, zirconia, iron oxides, boria, calcium oxide, zinc oxide, barium oxide thoria, aluminum phosphate gel, polyvinylchloride and substituted polystyrene; and (b) contacting the fluorided support composition with a non-coordinating anion and a metallocene.
