摘　　要：本文研究了羟乙基纤维素（ＨＥＣ）、甲基丙烯酸甲酯（ＭＭＡ）和壬基酚聚氧乙烯醚丙烯酸酯（ＮＰＥＯ４Ａ，氧乙基数为４）的超声共聚反应，探讨了辐照时间、单体浓度等因素对共聚物水溶液表面活性和粘度的影响。制得了具有高表面活性、高粘度的ＨＥＣ／ＭＭＡ／ＮＰＥＯ４Ａ共聚物，这种新型高分子表面活性剂的最低表面张力为２９．８ｍＮ／ｍ，最低界面张力为１．６６ｍＮ／ｍ，１％的共聚物水溶液表观粘度为８．０７ｍＰａ·ｓ。The ultrasonic synthesis of tercopolymers from hydroxyethyl cellulose, HEC, methylmethacrylate, MMA, and surface active macromonomer nonylphenylpolyoxyethyleneacrylate, NPEO 4A (EO number 4) is conducted with varying concentrations of MMA and NPEO 4A and reaction time 20—60 min at 20℃ in laboratory. A series of polymer surfactants are obtained with high surface activity as well as high viscosifying capacity in water. For a tercopolymer of hydrophobicity and hydrophilicity in some balance, following execllent properties are determined: surface tension 29.8 mN/m (1.0%); interface tension 1.66 mN/m (0.5% solution/a diluted curde oil); apparent viscosity 8.07 mPa·s (1.0% solution at 25℃ and 192 s -1 ).
