Abstract: Disclosed is a dispersible low molecular weight grafted random ethylene/propylene copolymer that forms very stable aqueous dispersions. The random ethylene/propylene copolymer used to prepare the grafted random ethylene/propylene copolymer contains at least 0.5 but less than 7 weight percent ethylene randomly distributed in polypropylene. The grafted random ethylene/propylene copolymer of high acid number is produced by the reactive extruding of reactants in a screw extruder.

Abstract: 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.
