All process" including irradiation doseEstoragetimeEreaction temperature and graft co-polymerization£@was carried out in air. The effects of several reactionconditions was investigated and discussed in detailed. The results show that grafting can well be achievedwithout purging oxygen and the grafted materials show a promising future in ion-adsorption. In this reactionsystemfsuitable storage times play little effect on grafting yield. The MohriS concentration and temperatureare the most important reaction condition ingrafing. The favorable MohriS concentration is about 0. 08%2-keep the reaction temperature at 60C can achieve the best result. C )ptional reaction condition wasgeneralized for large- scale production of the desired materials.Key words Graft co-polymerization2EB pre- iradiationfowdered isotactice polypropylene£Acrylic acid中国煤化工MHCNMHG
