Acrylic acid (AA) and sodium styrene sulfonate (SSS) were grafted onto high-density polyethylene film by preirradiation, and we prepared an ion exchange membrane including strong acid and weak acid groups. The effect of pH on grafting yield was studied. In simultaneous radiation method G t and G s decrease with pH either HDPE grafted AA and SSS or AA-g-HDPE membrane grafted SSS. In preirradiation method G t and G s respectively increase with pH, and the highest grafting yield was observed at pH… CONTINUE READING
