Abstract:
Disclosed herein are dual catalyst compositions containing an unbridged metallocene compound, a bridged metallocene compound, a chemically-treated solid oxide, and an optional co-catalyst. These catalyst compositions can be used for the oligomerization of propylene to produce an oligomer product. For example, a heavy propylene oligomer can be recovered from the oligomer product, and the heavy propylene oligomer can be characterized by a high flash point and viscosity index, and a low pour point.

Claim (Index 37):
The process of  claim 35 , wherein:\n catalyst component I comprises an unbridged metallocene compound having formula (I): and\n catalyst component II comprises a bridged metallocene compound having formula (II): \n wherein:\n M 1  and M 2  are Zr; \n Cp A  and Cp B  independently are a cyclopentadienyl group or an indenyl group; \n Cp C  and Cp D  independently are a cyclopentadienyl group; \n E is C or Si; \n each R 1  independently is H or a C 1  to C 18  hydrocarbyl group; and \n each X independently is a monoanionic ligand.
