摘　　要：以甲基丙烯酸和丙烯磺酸钠为单体、过硫酸铵溶液为引发剂合成聚合物分散剂(PMS)。最佳合成条件:单体总质量为60g,甲基丙烯酸和丙烯磺酸钠的摩尔比为3.0,过硫酸铵溶液加入量为12g,亚硫酸氢钠加入量为1g,反应温度为75℃。对最佳条件下制得的PMS进行应用实验,当100g陶瓷氧化铝粉末中PMS加入量为0.5g时,浆料的黏度较小,分散效果良好。PMS属于非晶态聚合物,热稳定性良好,相对分子质量为2 127。Polymer dispersant （PMS） was synthesized using methylacrylic acid and sodium allylsulfonate as monomers and ammonium persulphate solution as initiator. The optimum conditions are as follows： total mass of monomers 60 g, mole ratio of methylacrylic acid to sodium allylsulfonate 3.0, dosage of ammonium persulphate solution 12 g, dosage of sodium bisulphite 1 g, reaction temperature 75 ℃. The application experiment on PMS synthesized under the optimum conditions was carried out. When the dosage of PMS is 0.5 g in 100 g alumina powder, the viscosity of slurry is smaller and the dispersion effect is good. PMS is a kind of amorphous polymer with good thermal stability and 2 127 of relative molecular mass.
