Abstract:
1. A process for making higher olefin copolymers, wherein the process comprises contacting: (i) from about 20 to about 99.9 mol % of at least one C iii) from about 0.1 to about 80 mol % of propylene; wherein the contacting occurs 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: 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, halogens, dienes, amines, phosphines, ethers, and a combination thereof, (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 R each R two R or 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 R each R each R each R T is a bridging group represented by the formula R each R two R further provided that any of adjacent R or wherein 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 halogens, dienes, amines, phosphines, ethers, or a combination thereof; each R each R wherein the higher olefin copolymer has an Mn of 300 g/mol or more (measured by wherein the higher olefin copolymer has at least 40% allyl chain ends.
