采用烯丙基聚氧乙烯醚(APEO)为原料制备了大分子单体羧酸盐封端聚氧乙烯醚(APEC)并与小分子单体丙烯酸(AA)聚合生成聚合物阻垢剂AA/APEC.通过静态阻垢实验确定了聚合反应单体最佳质量比为m(APEC)∶m(AA)=1∶4,合成的阻垢剂AA/APEC在20 mg/L时阻碳酸钙垢率为91.2％,与有磷阻垢剂PBTC阻碳酸钙垢性能相当,但优于市场其他阻垢剂阻碳酸钙能力,且聚合物AA/APEC只含碳、氢、氧、钠元素,无氮、磷污染,可以充当循环水用环保型阻碳酸钙垢阻垢剂.扫描电镜和透射电镜研究表明:羧基是影响聚合物AA/APEC阻止碳酸钙垢形成的主要因素,而乙烯氧基的亲水性则是阻止碳酸钙垢沉积的主要原因.
