Synthesis of PoIyolefin-g-Poly(ethylene oxide).by-Reacting Maleic Anhydride Modified Polypropylene or Poly(propylene-co-ethylene) with Hydroxy-terminated Poly(ethylene Oxide) in the Melt

摘要

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