<p>Process for producing polyolefins, comprising the following steps: a) grafting of acid groups onto polyolefins by means of a graftable monomer bearing at least one functional group chosen from a carbonyl and an acid anhydride, optionally in the presence of another graftable monomer bearing a vinyl unsaturated group and, optionally, one or more aromatic rings; b) purification, consisting in removing at least some of the graftable monomer bearing at least one functional group chosen from a carbonyl and an acid anhydride that has not reacted with the polyolefins; c) neutralization of the acid groups by at least one neutralizing agent. Polyolefin obtained.</p> |
