| titleOfInvention | Process to produce ethylene propylene copolymers |
| abstract | This invention relates to a copolymer prepared using two or more non-coordinating anion activators comprising a first C2 to C12 alpha olefin (such as ethylene), a second C3 to C12 alpha olefin (such as propylene) different from the first alpha olefin, and diene (such as ethylidene norbornene and/or vinyl norbornene), where the polymer has: a) first alpha olefin (ethylene) content of 35 to 90 mol%; b) second alpha olefin (propylene) content of 9.8 to 64.8 mol%; c) diene content of 0.2 to 5 mol%; d) a branching index g'ave of 0.95 or more; e) a complex viscosity ratio (eta*(0.01rad/s)/eta*(100rad/s), at 125°C) greater than 1.1 *Y0, where Y0 = Y1+{[(Y2-Y1)/(X2-X1)](X0-X1)}, where X0 is the wt% of a first non-coordinating anion activator, NCA1, used to prepare the copolymer (based upon weight of NCA1 and a second non-coordinating anion activator, NCA2, used to prepare the copolymer), X1 = 0, X2 =100, Y1 = complex viscosity ratio of polymer made with 100% NCA1 and 0% NCA2, Y2 is complex viscosity ratio of polymer made with 100% NCA2 and 0% NCA1, where NCA1 has an Mw lower than the Mw of NCA2; f) an Mw/Mn of 4.0 or less; g) a melting point of 30°C or less; and h) a Composition Distribution Breadth Index of 50% or more. |
