| titleOfInvention | NOVEL CATALYST FOR PRODUCING VINYL-TERMINATE POLYMER AND METHOD OF USING THE SAME |
| abstract | The present invention relates to a homogeneous method for preparing a vinyl terminated propylene polymer, the method comprising contacting propylene under polymerization conditions with a catalyst system comprising an activator and at least one metallocene compound. The metallocene compound is represented by formula (I), wherein M is hafnium or zirconium; each X is independently a hydrocarbyl group having 1 to 20 carbon atoms, a hydride, an amide , Alkoxide, sulfide, phosphide, halide, diene, amine, phosphine, ether, and combinations thereof (two Xs may form part of a fused ring or ring system); each R 1 is independently a C 1 -C 10 alkyl group; each R 2 is independently a C 1 -C 10 alkyl group; each R 3 is Independently, is hydrogen; each R 4, R 5 and R 6 are independently hydrogen or substituted or unsubstituted hydrocarbyl group, heteroaryl or hetero atom-containing group,; T is an bridging group Each R 7 is independently hydrogen, halogen, or C 1 -C 20 hydrocarbyl; the two R 7 are cyclic structures containing aromatic, partially saturated, or saturated cyclic or fused ring systems; Provided that any of the adjacent R 4 , R 5 and R 6 groups may form a fused ring or a multi-centered fused ring system, which ring is aromatic, partially saturated Or it may be saturated.
