聚合表面活性剂的合成及其应用

Synthesis and application of polymeric surfactants

综述了近二十年来聚合表面活性剂的合成及主要应用,详细阐述了国内外对低聚表面活性剂在合成、界面吸附和溶液聚集行为方面的研究进展。已有的研究结果表明,中低分子质量的线性聚合表面活性剂不但具有很高的界面活性,可以使原油/水的界面张力达到超低,而且兼具一定的黏度,在三次采油上将具有很大的应用前景。

Recent progresses in the synthesis and main applications of various kinds of polymeric surfactants during the past 20 years were reviewed.The development of oligomeric surfactants in terms of synthesis,interfacial adsorption and aggregation behavior was described in details.Research results showed that the linear polymeric surfactants of medium and low molecular weight not only have excellent interfacial activities for lowering the interfacial tension between the crude oil and water to an ultra extent,but also performs certain viscosity characteristics.Therefore there will be broad prospects for application of such surfactants in the field of enhanced oil recovery.
