    • 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.
    • 制备聚烯烃的方法,包括以下步骤:a)通过具有至少一个选自羰基和酸酐的官能团的可接枝单体将酸基接枝到聚烯烃上,任选地在另一种带有乙烯基的可接枝单体的存在下 不饱和基团和任选的一个或多个芳族环; b)纯化,其包括除去至少一些具有至少一个选自与聚烯烃不反应的羰基和酸酐的官能团的可接枝单体; c) 通过至少一种中和剂中和酸基团。得到聚烯烃。
