Maleic Anhydride Grafted Polyolefins

Polymers such as PP, PE and EPDM can be grafted in an extruder with maleic anhydride (MA) using specific organic peroxides. When separately dosing organic peroxide and MA, the choice of peroxide depends on its solubility in the polymer and extrusion temperature applied. AkzoNobel offers various organic peroxides which can be used for this separate dosing technique.

One of our latest products to be introduced to the market is Perkadox® PF-DBM25, which has the MA monomer incorporated in the peroxide molecule.

This graft technology, developed by AkzoNobel, improves compatibility (solubility) of the raw materials with the polymer and avoids the presence of free MA in the end product. MA grafted polymers can be used as adhesives in glass fiber reinforced PP (GFR-PP) and tie-layer PE film, and as compatibilizer for non-miscible polymers, nanocomposites and wood fiber PP composites.
