Abstract:
1. 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 each R each R each R R R each R N is nitrogen; T is a bridge; each R 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.
