Abstract
Process for functionalizing an ethylene-based (co)polymer comprising the step of contacting an ethylene-based (co)polymer at a temperature in the range 100-250° C. with an azide of formula (I) wherein Y is either (Ia) or (Ib) m is 0 or 1, n is 0 or 1, n+m=1 or 2, and X is a linear or branched, aliphatic or aromatic hydrocarbon moiety with 1-12 carbon atoms, optionally containing heteroatoms.
