Title: STUDY ON THE PREPARATION OF BIFUNCTIONAL CATION-EXCHANGE MEMBRANES INDUCED BY ELECTRON BEAM RADIATION METHOD
Abstract: A study was made on the preparation of the cation-exchange membranes including sulfonate and carboxylic acid groups by pre-irradiation grafting of acrylic acid(AA) and sodium styrene sulfonate(SSS) onto high-density polyethylene(HDPE).The grafting yield was found to be strongly dependent on the synthesis conditions such as monomers total concentration,pH,grafting temperature and type of solvent.An easy control over the grafting yield could be achieved by proper selection of reaction conditions.Water absorbance of grafted membranes increases with the increasing of grafting yield.X-ray test found that the grafted membranes show a decrease in crystallinity depending on the grafting yield.
