ABSTRACT:
An extruder process for grafting ethylenically unsaturated monomers onto polyolefin polymers through the use of peroxide initiators without evidencing degradation of the base polymer whereby the components are concurrently melted and homogeneously mixed in an intensive mixing zone of an extruder, passed into a reduced pressure zone to remove excess monomer and passed through the remainder of the extruder process.
