    Abstract: A two component catalyst activator comprises: 1) a Lewis acidic organoboron (or an orgonoaluminum) component; and 2) a component defined by the formula AOSO2R wherein A is a pseudo cationic group and R is a hydrocarbyl or substituted hydrocarbyl. The catalyst activator is used in combination with a transition metal catalyst for the polymerization of olefins. The catalyst activator provides improved catalyst activities. It is especially useful in solution polymerizations because of desirable solubility characteristics in comparison to the borate salts used in prior activators.

    Abstract: This application discloses triphenyl carbenium NCA's as catalyst activators for a class of asymmetrically bridged hafnocene catalyst precursors. These catalsyst precursors are activated into olefin polymerization catalysts and are suitable for gas, solution, and slurry-phase polymerization reactions. The disclosed bridge is methylenyl- or silanylenyl-based and is optionally, alkyl or aryl substituted. The catalytic activity of the disclosed hafnocene catalyt precursors is substantially enhanced over identical catalysts that are activated with other activators.

    Abstract: By controlling the hold up times, concentrations and temperatures for mixing the components of aluminum, titanium and magnesium based catalyst for solution polymerization it is possible to prepare a catalyst having a high activity, which prepares high molecular weight polyolefins. Generally, a catalyst loses activity and produces lower molecular weight polymer at higher temperatures. The catalyst of the present invention permits comparable polymers to be produced with higher catalyst activity and at higher reaction temperatures by increasing the concentration of the components used during the preparation of the catalyst.
