以甲基烯基聚氧乙烯醚(TPEG)、衣康酸(IA)为原料,在氧化/还原引发剂体系作用下进行自由基共聚,合成IA/TPEC阻垢剂.通过红外光谱(FTIR)、核磁共振氢谱(1H NMR)等方法对阻垢剂结构进行表征.考察了单体配比、引发剂的种类和聚合条件等对合成IA/TPEC阻垢剂性能的影响.实验结果表明:当m(IA):m(TPEC)为1:1,在110℃下聚合1.5 h,采用过硫酸铵/次亚磷酸钠为引发剂体系,合成的IA/TPEC对CaCO3和Ca3(PO4)2的阻垢率分别为90.19%和92.71%,阻垢效果优于市售阻垢剂.

IA/TPEC was synthesized with itaconic acid (IA) and methyl alkenyl polyoxyethylene ether (TPEG) as raw materials,and initiated free radical copolymerization in the presence of oxidation/ reduction system. The product was characterized by FTIR and1H NMR. The influence of monomer mass ratio,type of initiator and polymerization conditions was investigated. The results showed that when monomer mass ratio of IA to TPEC was 1:1,polymerization temperature was 110℃, polymerization time was 1.5 h,initiating system was ammonium persulfate and sodium hypophosphite, the inhibition rate on CaCO3 and Ca3(PO4)2 of IA/TPEC reached 90.19% and 92.71%,respectively.The scale inhibiting efficiency of IA/TPEC was better than that of market inhibitors.
