摘　　要：以异丁烯醇聚氧乙烯醚(HPEG)、衣康酸(IA)为原料,在过硫酸铵-次亚磷酸钠引发剂作用下进行自由基共聚,合成阻垢剂IA-HPEC。采用FT-IR、1 H-NMR等方法表征IA-HPEC阻垢剂结构,采用扫描电镜(SEM)观察阻垢后形成的CaCO3晶体形貌。通过静态阻垢性能实验,考察了单体配比、聚合条件、氧化剂滴加方式及用量对合成的IA-HPEC阻垢剂阻垢性能的影响。结果表明,在m(IA)/m(HPEC)=1、聚合温度110℃、聚合时间1.5h、分批滴加氧化剂的最佳聚合条件下,合成的共聚物IA-HPEC对CaCO3的阻垢率为93.9%,优于市场含磷阻垢剂,具有较好的经济与环境效益。IA-HPEC copolymer was synthesized with itaconic acid （IA） and isobutylene alcohol ethoxylates （HPEG） as raw material, ammonium persulfate-sodium hypophosphite as initiator. The product was characterized by FT-IR and 1H-NMR. The influences of monomer mass ratio, polymerization conditions, oxidant dropping method and dosage on inhibition performance of synthesized IA-HPEC copolymer was investigated by the static scale inhibition experiment. The disordered CaCO3 crystal in the presence of IA-HPEC was analyzed by SEM. The results showed that the IA-HPEC synthesized under the optimal conditions of m （IA）/m （HPEC） = 1, polymerization temperature 110℃, polymerization time 1.5 h and oxidant dropping in batches, exhibited excellent ability to control CaCO3 scale, when the inhibition rate on CaCO3 reached 93.9%. The scale inhibiting efficiency of IA-HPEC was better than market inhibitors, indicating that IA-HPEC had good economic and environmental benefits.
