Description

Acrylic acid (AA) and sodium styrene sulfonate (SSS) were grafted onto high-density polyethylene film by preirradiation, and the authors 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 Gt and Gs decrease with pH either HDPE grafted AA and SSS or AA-g-HDPE membrane grafted SSS. In preirradiation method Gt and Gs respectively increase with pH, and the highest grafting yield was observed at pH=2.80 then Gt and Gs decrease with pH. Viscidity of grafting system was changed due to adjusting of pH, so that diffuse rate of monomers into matrix was affected
