    Water Soluble and Amphiphilic Polymers: 9. Studies on monolayer formation of a novel acrylamido-amphilic monomer and its amphiphilic polymer

    • 摘要: 本文对新型两亲单体,2-丙烯酰胺基十六烷磺酸(AMC_(16)S),及其两亲聚合物PAMC_(16)S在空气-水界面上形成单层膜的特点进行了研究。AMC_(16)S可通过在亚相中添加Ca~(2+)或Cd~(2+)等多价阳离子在界面上原位生成不溶性磺酸盐的方法获得满意的成膜行为。PAMC_(16)S不溶于水,可直接成膜。发现,PAMC_(16)S的成膜行为与亚相的性质明显相关。纯水亚相下PAMC_(16)S的极限单体链节面积较大,如亚相含有Ca~(2+)或Cd~(2+),极限面积明显缩小,说明烷基碳氢链的排列趋向紧密。

       

      Abstract: The monolayer formation on the air-water interface of a new amphiphilic monmer, 2-acrylamidohexadecylsulfonic acid (AMC16S), and the amphiphilic polymer PAMC_(16)S has been investigated. The spreading of the watersoluble amphiphilic monomer can be achieve
