Patent ID: 10494456

Abstract:
A process to form an ethylene-based polymer, in the presence of at least one free-radical, said process comprises at least the following: polymerizing a mixture comprising ethylene in a reactor configuration comprising at least four reaction zones, and comprising at least three ethylene feed streams; and wherein the ratio of (RLCBf40%), in percent, of the LCB content of the “first 40 wt % of the total polymer formed” to the “total LCB content in the final polymer” is ≤29%; and wherein the amount of ethylene, and optionally one or more comonomers, and optionally one or more CTAs, fed to the first reaction zone, is from 20 mole % to 70 mole %, based on the total moles of ethylene, and optionally one or more comonomers, and optionally one or more CTAs, fed to the polymerization.
