Abstract: The acrylamide/NbenzylNnhexadecylacrylamide/sodium acrylates terpolymerP(AM/BHAM/NaA) was synthesized using micellar polymerization and the synthetic scheme was optimized. The amphiphilic polymer has a critical aggregation concentration (CAC). Above CAC, P(AM/BHAM/NaA) forms network in aqueous solution. With the increase of polymer concentration, the hydrodynamic radius of it increases, and the apparent viscosity also increases. P (AM/BHAM/NaA) has good capability of crude oil emulsion. By studying the different concentrations of amphiphilic polymer on the properties of crude oil emulsion, it is found that with the increase of amphiphilic polymer concentration, the volume of network, formed by amphiphilic polymer in aqueous solution, increases and its emulsifying ability also is enhanced.

摘要： 通过自由基胶束共聚法制备了 N - 苄基 - N - n - 十六烷基丙烯酰胺/丙烯酰胺/丙烯酸钠三元共聚两亲聚 合物 - P( AM / BHAM / N a A) , 并优化了合成方案。该聚合物具有临界聚集浓度( CAC) , 当该两亲聚合物质量浓度高 于7 0 0m g / L时, P( AM / BHAM / N a A) 在水溶液中形成聚集体, 并随着聚合物质量浓度的增加聚集体的流体力学半 径增加, 表观黏度也随之增加。P( AM / BHAM / N a A) 具有良好的原油乳化能力, 研究了不同质量浓度的两亲聚合物 对原油乳化性能。结果表明, 随着两亲聚合物质量浓度的升高, 在水溶液中形成聚集体的体积增大, 空间网络结构 增大, 乳化能力升高。
