Abstract

PURPOSE:A polyolefin resin is kneaded together with a condensation catalyst in the former-stage extruder and the composition is fed into latter-stage extruder wherein the number of screw revolution is controlled to make the pressure in the latterstage extruder negative thus enabling the injection of a grafting agent with no use of pump.
