摘要
制备了三种互贯网络弱碱性阴离子交换树脂(NR系列)。树脂的骨架为聚氯乙烯(PVC)、丙烯晴(AN)、苯乙烯(st)和二乙烯苯(DVB)的共聚物,NR系列弱碱树脂由共聚物经乙胺、二乙烯三胺和三乙烯四胺胺化而得。用元素分析、红外光谱、中和滴定和pH曲线法等技术测定研究了所得弱碱树脂的结构和性能。
Three kinds of weak basic anion exchange resins(NR series)with interpenetrating networks have been prepared.The networks of the resins contain the copolymers of PVC,AN,ST and DVB,and the copolymers are aminated by ethylene diamine,divinyl triamine and trivinyl tetramine. The structurs and properties of these resins are studied on the basis of ele- mental analysis,infra-red spectrometry,acid-base titration and PH titration curve.Experimental results indicate that the NR series resins behave high exchange capacity and low swelling coeffieient,the engineering flow is easy and the toxicity is very small.So it has quite a industrial use value.
