  • 摘要: 本文以硝酸铈铵为引发剂,制得了甲基丙烯酸甲酯与交联玉米淀粉的接枝共聚物,当〔Ce4+〕为5×10-3mol·L-1、〔MMA〕为7.52×10-1mol.L-1,于50℃反应4h,所得接枝共聚物的接枝率和接枝效率都较高。将接枝共聚物分别与NH2OH及KH2NH2反应,所得的产物具有对Cu2+,Pb2+,Zn2+等金属离子的吸附能力。
    Abstract: The graft copolymerization of methyl methacrylate (MMA)onto crosslinked corn starch with eerie ammonium nitrate as the initiator was studied. It wag shown that the percent of grafting(G%)and graft efficiency (E%) were considerably affected by[Ce4+G% and E% were obtained at [Ce4+-3mol·L-1, CMMAD of 7.52 × 10-1mol·L-1 at 50℃ for 4h. It was found that the graft copolymer can be modified with hydroxylamine and hydrazine, respectively.The modified copoly-mers can adsorb metal ions of Cu2 Pb2+, Zn2+ , andothers.
