CATALYST PRECURSOR COMPOSITION, AND METHOD OF MAKING THE SAME |
摘要 |
A catalyst precursor composition comprises the reaction product of a cation exchange resin containing trityl carbonium ions contacted with a metallocene. The process of producing the reaction product of a cation exchange resin containing trityl carbonium ions contacted with a metallocene comprises (1) providing a cation exchange resin which has cations, (2) contacting the cation exchange resin with a solution comprising a trityl halide complex and solvent therefor to form an intermediate; and (3) contacting the intermediate with a metallocene, preferably a zirconocene salt. The resulting composition can be used to form ethylene resins in an alumoxane free system. |
