A PROCESS OF CONTROLLED RADICAL GRAFTING OF A POLYOLEFIN

摘要

The present invention relates to a controlled radical grafting process of a polyolefin derived from monomeric units including a 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=CRIR2 group in which at least one of R1 and R2 is an electron acceptor functional be performed continuously in an extruder or discontinuously in a mechanical mixer.
