水溶性聚合物和两亲聚合物19．磺化液体聚丁二烯──种新型液膜用表面活性剂

Water-Soluble and Amphiphilic Polymers: 19 Sulfonated Liquid Polybutadiene-a New kind of Surfactants Used in liquid Surfactant Membrane Separation

摘要: 一种新的聚工二烯型表面活性剂ＬＹＦ经液体聚了二烯磺化方法制备而得，并应用于液膜分离研究之中。发现无论内水相是酸性还是碱性，由该表面活性剂制得的Ｗ／Ｏ型乳状液在稳定性、溶胀率和破乳诸方面均具有令人满意的综合性能。为深入了解液膜的稳定性，我们测定了处于两种水相间的双分子膜的强度。发现由ＬＹＦ所形成的双分子膜具有最大的膜强值，优于聚异丁烯型的表面活性剂ＥＣＡ４３６０和ＥＭ３０１．

Abstract: New Polybutadiene-based surfactants LYF were synthesized by sulfonation of liquidPolybutadiene, and they can be used in liquid surfactant membrane (LSM) separation process. It wasfound that LYF surfactants had a satisfactory overall property as regards st
