In order to obtain required polymer materials

acrylic acid was grafted onto powdered isotactic polypropylene by electron beam pre-irradiation technique.All process (including irradiation dose

storage time

reaction temperature and graft-co-polymerization) was carried out in air.The effects of several reaction conditions was investigated and discussed in detailed.The results show that grafting can well be achieved without purging oxygen and the grafted materials show a promising future in ion-adsorption.In this reaction system

suitable storage times play little effect on grafting yield. The Mohr's concentration and temperature are the most important reaction condition ingrafting.The favorable Mohr's concentration is about 0.08%

keep the reaction temperature at 60℃ can achieve the best result.Optional reation condition was generalized for large-scale production of the desired materials.
