摘　　要：研究了在超声辐照下羟乙基纤维素 (HEC)与活性大单体壬基酚聚氧乙烯醚丙烯酸酯 [NPEOnA (n =4 ,7,10 ,15 ) ]的共聚反应 ,通过IR、DSC研究了所得共聚物的结构 ,并对所制备的HEC/NPEOnA系列共聚物的水溶液性能进行了研究。结果表明 ,在超声辐照下HEC可以和NPEOnA活性大单体进行共聚反应而制得表面活性较高的共聚物 ,这种共聚物可作为高分子表面活性剂 ,其最低表面张力为 31.5mN/m ,最低界面张力 (5 %大庆原油煤油 /水 )为 1.0 5mN/m ,1%的共聚物水溶液表观粘度为 2 .5 0mPa·s。The ultrasonic polymerization of HEC/NPEOnA and the copolymer properties in aqueous solution were studied. The results show that the HEC/NPEOnA copolymer with high activity can be obtained by ultrasonic irradiation. The copolymers can be used as polymer surfactants. The lowest surface and interface tension of copolymer are 31.5 mN/m and 1.05 mN/m, apparent viscosity of 1% the copolymer aqueous solution is 2.50 mPa&middots. The copolymers were characterized by IR and DSC. The effects of macro-monomer with numbers of hydrophilic chains in the feed on copolymer properties in aqueous solution were also be studied.
