【摘要】 大孔球状PVC经苯乙烯的自由基互穿聚合反应改性得PS PVC大孔互贯树脂 ,再与有机胺反应制得了PS PVC互贯含氮大孔吸附树脂 .研究表明 ,所得吸附树脂对脲酸的吸附率可达 5 0 %以上 ,在清除体液中过量脲酸方面具有应用潜力 .同时对吸附树脂含氮量与吸附脲酸性能的关系以及其它因素的影响也进行了探讨

【Abstract】 A PS/PVC macroreticular bead polymer material was synthesized by interpenetrating polymerization of styrene into macroporous poly(vinyl chloride)bead, i.e. PS/PVC MR IPN matrix.A series of the adsorption resins were prepared by further reaction of PS/PVC MR IPN matrix with ethylenediamine,diethylenetriamine and triethylenetretamine.The resulting resins were applied to adsorb uric acid.The results show that these resins have higher sorption percentage,adsorption capacities and faster sorption speed for uric acid.The composition and properties of the resulting resins,as well as the influence factors for the eliminating uric acid character were investigated.
