Abstract

Process for modifying a polyolefin grafted with acid or anhydride groups, by at least partial neutralization of these groups with at least one neutralizing agent comprising an organic salt (1) that releases an organic acid (I) during the neutralization, according to which the organic acid (I) derived from the neutralization of the grafted polyolefin is reacted with at least one inorganic salt (2).Modified polyolefin (that can be) obtained by the process described above.Polymeric composition containing (A) at least one polymer, and (B) at least one modified polyolefin (that can be) obtained by the process above.Article comprising the modified polyolefin or the composition described above.
