Abstract: Disclosed herein are catalyst compositions containing bicyclic bridged metallocene compounds. These catalyst compositions can be used for the polymerization of olefins. For example, ethylene polymers produced using these catalyst compositions can be characterized by low molecular weights and high melt flow rates, and can be produced without the addition of hydrogen.

Abstract: Sulfated bentonite compositions are characterized by a total pore volume from 0.4 to 1 mL/g, a total BET surface area from 200 to 400 m2/g, and an average pore diameter from 55 to 100 Angstroms. The sulfated bentonite compositions also can be characterized by a d50 average particle size in a range from 15 to 50 μm and a ratio of d90/d10 from 3 to 15. The sulfated bentonite compositions can contain a sulfated bentonite and from 10 to 90 wt. % of colloidal particles, or the sulfated bentonite compositions can contain a sulfated bentonite and from 0.2 to 10 mmol/g of zinc and/or phosphorus. These compositions can be utilized in metallocene catalyst systems to produce ethylene based polymers.
