<p>Disclosed is a process for the production of low molecular weight grafted polyolefins in which a molten polyolefin is grafted by reactive processing in a screw extruder at an elevated pressure. The molten polyolefin has a low viscosity and flows easily around the screw, thus the pressure is maintained in the screw extruder apparatus by the use of a pressure control device at the exit end of the extruder.</p> |
