摘要: 以（NH4）2S2O8-Na2SO3作为引发体系，合成羟乙基纤维素丙烯酰胺接枝聚合物，着重讨论了羟乙基纤维素含量对相对分子质量的影响，通过正交实验得出聚合物相对分子质量影响因素依次为：HEC含量〉引发剂用量〉初始温度；利用电导率仪和旋转粘度计对接枝聚合物水溶液的电导率和剪切粘度进行测定，结果表明接枝聚合物的抗盐性和耐温性都比单体有了明显提高。Abstract: Synthesis of HEC-AM graft copolymer initiated by (NH_4)_2S_2O_8-Na_2SO_3. The effect of the different concentration of HEC and others factors on molecular weight of HEC-AM graft polymer was discussed. The results show that the effect on molecular weight o
