Summary: | A process to form a "functionalized ethylene-based polymer" from a first composition comprising an ethylene-based polymer and at least one polar compound, and at least one peroxide, said process comprising at least the following: a) thermally treating the first composition, in at least one extruder comprising at least one barrel, to form the functionalized ethylene-based polymer; b) extruding the functionalized ethylene-based polymer, in melt form, to form an extrudate; c) cooling the extrudate; and d) pelletizing the extrudate; and wherein the "efficiency of the peroxide consumption, after the thermal treatment, is ≥ 91 wt% within the at least one extruder; and wherein the "normalized feed rate" at which the process is run is ≥ 0.0018 (lbs/hr)/(mm) |
