This invention relates to a homogenous process for making a vinyl terminated propylene polymer, wherein the process comprises: contacting, propylene, under polymerization conditions, with a catalyst system comprising an activator and at least one metallocene compound, where the metallocene compound is represented by the formula: where: M is hafnium or zirconium; each X is a group bound to M as described herein; each R1 and R2 is, independently, a C1 to C10 alkyl group; each R3 is, independently, hydrogen; each R4, R5, and R6, is, independently, hydrogen or a substituted or unsubstituted hydrocarbyl group, a heteroatom or heteroatom containing group; T is a bridging group as described herein; and further provided that any of adjacent R4, R5, and R6 groups may form a fused ring or multicenter fused ring system where the rings may be aromatic, partially saturated or saturated, wherein the activator comprises a non-coordinating anion.
