摘要(Abstract)：

针对油田化学驱污水难处理问题，采用水溶液自由基胶束聚合法，以聚合氯化铝(PAC)为无机组分，丙烯酰胺(AM)、丙烯酸丁酯(BA)为有机单体，合成一种新型无机-有机杂化高分子絮凝剂(PAC-P(AM-BA))。利用傅里叶变换红外光谱仪(FT-IR)、热重分析仪(TGA)、扫描电子显微镜(SEM)和比表面积分析仪(BET)对絮凝剂进行表征。结果表明，BA以化学键连接在聚丙烯酰胺(PAM)长链中，无机组分与有机组分之间以离子键连接。PAC-P(AM-BA)热分解温度为233.93℃，比表面积为30.351 m~2·g~(-1)。絮凝实验结果表明，PAC-P(AM-BA)最佳投加量为20 mg·L~(-1)，沉降时间为10 h，其絮体分形维数为1.733。在絮凝效能对比实验中，PAC-P(AM-BA)的平均除油率为90.3%，较阳离子聚丙烯酰胺(CPAM)和复配型絮凝剂(PAC+PAM)分别高出16.4%和29.0%。
