以氯乙酰化聚苯乙烯微球(PS-acyl-Cl)为大分子引发剂通过原子转移自由基聚合法(ATRP)引发亲水性单体丙烯酰胺(AM)和甲基丙烯酸缩水甘油酯(GMA)单体的共聚合,制得一种具有“柔性”的触角状亲水性环氧载体(PS-acyl-g-P(AM-co-GMA)),再经二乙醇胺(DEA)的环氧基开环胺化反应,得到一种含有多齿-五元螯合环的触角状亲水性羟胺树脂(PS-acyl-g-P(AM-co-GMA)-DEA).经过合成条件优化,结果表明,用乙醇和水组成的混合溶剂,溶剂量为V(Solv)/V(DEA)=3(体积比,下同),试剂用量为n(DEA)/n(epoxy)=2(摩尔比,下同),90℃反应约0.25 h,羟胺树脂增重率可以达到最大值58.6％,经元素分析可得其二乙醇胺担载量最高可以达到3.51 mmol/g,环氧基的转化率最大可以高达86.5％.且羟胺树脂的增重率随着环氧载体链长的增加而增加,而环氧基的转化率也随链长的增加而增加,后者表明,链长似乎有促进作用或邻近基团促进作用.将该螯合树脂直接用于硼的吸附,其饱和吸附量约为37.7 mg/g且树脂5min即可达到吸附平衡,与其它已报道的吸硼树脂相比,该树脂具有更高的吸附量和吸硼速率.
