The present invention relates to a controlled radical grafting process of a polyolefin derived from monomeric units including α-olefins. This process comprises the reaction of the polyolefin and at least one radical reaction initiator with a grafting system which comprises at least one grafting compound having an electron donator heterocyclic aromatic ring conjugated to at least one —HC═CRRgroup in which at least one of Rand Ris an electron acceptor functional group. The process can be performed continuously in an extruder or discontinuously in a mechanical mixer.
