    摘要： 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, independently, selected from the group consisting of hydrocarbyl radicals having from 1 to 20 carbon atoms, hydrides, amides, alkoxides, sulfides, phosphides, halides, dienes, amines, phosphines, ethers, and a combination thereof, (two X's may form a part of a fused ring or a ring system); each R1 is, independently, a C1 to C10 alkyl group; each 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; each R7 is, independently, hydrogen, halogen, or a C1 to C20 hydrocarbyl, and two R7 can form a cyclic structure including aromatic, partially saturated, or saturated cyclic or fused ring system; 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.
