Abstract

Abstract: 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 and ¹H 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.

摘要： 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。
