Grafting Maleic Anhydride onto LDPE with Melt Extrusion

Graft copolymerization of low density polyethylene (PE) with maleic anhydride (MAH) was studied by using a Brabender plasticorder.It was proved that the amounts of monomer,compounding monomers,initiator and compounding initiator had large effects on the degree of grafting (D.G.);The introduction of AA increased D.G.;Efficiency of grafting was the best when the ratio of DCP to BPO was third to one.
