The synthesis of amphipolar graft copolymers by reactive extrusion of maleic anhydride modified polypropylene or poly(propylene-co-ethylene) and α, ω-dihydroxy-poly(ethylene oxide) or α-hydro-ω-oxymethyl-poly(oxyethylene) was studied. The graft copolymers were characterized by Fourier transform infrared spectroscopy. Residence time of 30 min at 160°C was established to be sufficient for graft copolymer formation by melt extrusion.
