Abstract The graft copolymerization of acrylic acid (AA) onto low density polyethylene(LDPE) with benzoyle peroxide (BPO) as initiator in anhydrous xylene was studied. The influence factors, such as reaction temperature and the concentrations of AA and BPO, on the extent of grafting were discussed. The existence of graft copolymer was verified by infrared spectra (IR), X ray photoelectron spectroscopy (XPS), thin layer chromatography (TLC) and contact angle. The sodium salt of graft copolymer was prepared. |
