Acrylic acid was grafted to Polyethersulfone (PES) powders by liquid−phase simultaneous irradiation. Effects of grafting conditions, such as absorbed dose, Volume fraction of monomer, inhibitor (Cu,2+,) concentration, and pH of the grafting solution on degree of the grafting were investigated. Combined with gravimetric analysis, a working curve of grafting degree through FT−IR quantitative analysis was obtained. The highest grafting degree was achieved at dose of 25kGy, Volume fraction of monomer of 30% and inhibitor concentration of 0.004 mol/L. Greater degrees of the grafting could be obtained by adding increasing amount of hydrochloric acid to the system. Hydrophilicity of the grafted PES powders increased with higher degrees of the grafting.
