Abstract:
1. A process of producing a fluorided catalyst metallocene catalyst component comprising contacting a nitrogenous metallocene compound with a fluoriding agent comprising a Bronsted acid fluorided acid for a time sufficient to form a fluorided metallocene catalyst compound; wherein the mitrogenous metallocene compound comprises at least one nitrogenous leaving group “X”, wherein X is described by the formula —N(R α ) 2 , wherein each R α is independently selected from C 1 to C 10 alkyls, C 6 to C 20 aryls, C 7 to C 21 alkylaryls, C 7 to C 21 arylalkyls, and halide, carboxylate silyl or hydroxy-substituted versions thereof.
