摘　　要：为降低聚丙烯酸分散剂高分子链间的斥力,提高在粉体表面的吸附量,将丙烯酸丁酯同丙烯酸进行共聚,并探索了最佳制备工艺条件。实验结果表明,丙烯酸丁酯的加入确实可以提高吸附量,最佳制备工艺条件为:AA同BM的质量比为20∶12,过硫酸铵用量和亚硫酸氢钠用量都为3wt%,聚合温度为70℃。In order to improve adsorbance of dispersants on the surface of particulates, poly（butyl acrylate-co-acrylic acid） was synthesized , in addition, optimum technological conditions were studied. Results showed that butyl acrylate used as second monomer could increase adsorbance of dispersants, and AA ： BA=20 ： 12 （mass ratio）, ammonium persulfate and sodium hydrongen sulfite both 3.0 wt%,temperature 70℃ were optimum synthesis condition.
