Abstract:
A process to produce a composition of matter, said process comprising contacting at least one organometal compound, at least one treated solid oxide compound, and at least one organoaluminum compound to produce said composition,wherein said organometal compound has the following general formula(X.sup.1)(X.sup.2)(X.sup.3)(X.sup.4)M.sup.1wherein M.sup.1 is selected from the group consisting of titanium, zirconium, and hafnium, andwherein (X.sup.1) is independently selected from the group consisting of cyclopentadienyls, indenyls, fluorenyls, substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls, andwherein said substituents on said substituted cyclopentadienyls, substituted indenyls, and substituted fluorenyls, are selected from the group consisting of aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, and organometallic groups, and hydrogen; andwherein (X.sup.3) and (X.sup.4) are independently selected from the group consisting of halides, aliphatic groups, cyclic groups, combinations of aliphatic and cyclic groups, and organometallic groups, andwherein (X.sup.2) is selected from the group consisting of Group OMC-I or Group OMC-II, andwherein said organoaluminum compound has the following general formula,Al(X.sup.5).sub.n (X.sup.6).sub.3-nwherein (X.sup.5) is a hydrocarbyl having from 1-20 carbon atoms, andwherein (X.sup.6) is a halide, hydride, or alkoxide, andwherein ""n"" is a number from 1 to 3 inclusive;wherein said treated solid oxide compound is produced by a process comprising contacting at least one solid oxide compound with at least one electron-withdrawing anion source compound and at least one metal salt compound; andwherein said solid oxide compound is calcined before, during or after contacting said electron-withdrawing anion source or said metal salt compound.
