| 摘 要： | 本文进一步研究了环氧乙烷-环氧丙烷嵌段共聚物(L61和F68)、聚丙二醇(PPG)分别与十六醇(CA)、硬脂酸(SA)所形成的二元混合膜。根据对π-α实验结果的分析, 表明PPG-CA、PPG-SA、F68-SA和L61-SA的混合单分子膜是不相混溶的, 而L61-CA和F68-CA的混合单分子膜则是混溶的。

| Abstract: | Bicomponent monolayers of ethylene oxide-propylene oxide block copolymer (I) and polypropylene glycol (II) with stearic acid (III) or cetyl alcohol (IV) were studied at the air-water (40% NaNO3) interface by the compression isotherms at 20? The experimental data were analyzed in terms of the mol.-area additivity rule and the 2-dimensional phase rule. I was immiscible with III but miscible with IV while II was immiscible with both III and IV. |
