Abstract
A process to form a functionalized ethylene-based polymer composition comprises reacting an ethylene-based polymer composition in at least one extruder with at least one functionalization agent and at least one free radical initiator at a melt temperature of greater than or equal to 200° C. The functionalized ethylene-based polymer composition has a yellowness index (YI) value of less than or equal to 45 and a functionalization content of greater than or equal to 2.0 wt %, based on the weight of the functionalized ethylene-based polymer composition.
