| 摘 要： | 采用接枝β-CD抗盐碱功能单体与丙烯酰胺共聚后水解的方法制备超高相对分子质量抗盐碱星形聚合物。其最佳工艺参数为:偶氮二异丁腈质量浓度为50 mg/L、丙烯酰胺质量分数为25%、接枝β-CD抗盐碱功能单体质量分数为1.5%、引发温度为5℃、水解温度为90℃、水解时间为3.0 h。原子力显微镜形貌观察和红外光谱表征结果表明:抗盐碱星形聚合物S07313含有星核接枝β-CD功能单体。抗盐碱星形聚合物S07313的相对分子质量为2 450×104,其他基本理化性能都能达到油田应用指标的技术要求。当大庆模拟盐水中加入NaOH质量分数为1.0%的碱水时,抗盐碱星形聚合物S07313、HPAM3000和MO4000的表观黏度分别为42.40 mPa.s2、9.20 mPa.s和18.00 mPa.s。抗盐碱星形聚合物与表面活性剂重烷基苯磺酸盐的配伍性优良。图10表3参20
