Highly grafted ethylene polymer, highly grafted ethylene polymer composition, and formation process thereof

摘要

The process of forming the functionalized ethylene-based polymer composition includes: melting the ethylene-based polymer composition in at least one extruder with at least one functionalizing agent and at least one free radical initiator at 200 ° C or higher. Including reacting at temperature. The functionalized ethylene-based polymer composition has a yellowing index (YI) value of 45 or less and a functionalized content of 2.0% by weight or more based on the weight of the functionalized ethylene-based polymer composition.
