摘　　要：以H2O2-NaHSO3为引发剂,在超声波辅助下引发丙烯酸单体聚合,研究了单体浓度、引发剂用量、反应温度等对单体转化率和聚丙烯酸钠分子量的影响。结果表明:控制单体浓度30%、引发剂用量4.0%、反应温度60℃,可制得聚丙烯酸钠的相对分子量在2000～3000之间。Polyacrylic acid was synthesized with H2O2- NaHSO3 as initiator and microwave as assistant. It was investigated in details that the effects of monomer concentration, initiator concentration and reaction temperature on monomer conversion and molecular weight. The low molecular weight polyacrylic acid sodium（2000-3000） was got by monomer concentration 30 %, initiator concentration 4.0 % and reaction temperature 60 ℃.
