Patent ID: 8735502

Claim:
A process to make a functionalized co-oligomer, comprising 1) a first homogenous process for making a propylene co-oligomer, said first process having productivity of at least 4500 g/mmol/hr, wherein the first process comprises: contacting, at a temperature of from 35° C. to 150° C., propylene, 0.1 to 70 mol % ethylene and from 0 to about 5 wt % hydrogen in the presence of a catalyst system comprising an activator and at least one metallocene compound represented by at least one of the formulae: where: Hf is hafnium; each X is, independently, selected from the group consisting of hydrocarbyl radicals having from 1 to 20 carbon atoms, hydrides, amides, alkoxides, sulfides, phosphides, halogens, dienes, amines, phosphines, ethers, and a combination thereof, and two X's may form a part of a fused ring or a ring system; each Q is, independently carbon or a heteroatom; each R 1 is, independently, a C 1 to C 8 alkyl group, R 1 may the same or different as R 2 ; each R 2 is, independently, a C 1 to C 8 alkyl group; each R 3 is, independently, hydrogen, or a substituted or unsubstituted hydrocarbyl group having from 1 to 8 carbon atoms, provided that at least three R 3 groups are not hydrogen; each R 4 is, independently, hydrogen or a substituted or unsubstituted hydrocarbyl group, a heteroatom or heteroatom containing group; R 5 is hydrogen or a C 1 to C 8 alkyl group; R 6 is hydrogen or a C 1 to C 8 alkyl group; each R 7 is, independently, hydrogen, or a C 1 to C 8 alkyl group, provided that at least seven R 7 groups are not hydrogen; N is nitrogen; T is a bridge; each R a , is independently, hydrogen, halogen or a C 1 to C 20 hydrocarbyl, and two R a can form a cyclic structure including aromatic, partially saturated, or saturated cyclic or fused ring system; and further provided that any two adjacent R groups may form a fused ring or multicenter fused ring system where the rings may be aromatic, partially saturated or saturated, and 2) a second functionalizing process comprising contacting the co-oligomer produced in the first process with a heteroatom containing group.
