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-a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.
Bi-component monolayers in which polyoxyethylene-polyoxypropylene polyols (Pluronic polyols L61 and F68) or polyoxypropylene glycol (PPG) was used as one of the components and stearic acid (SA) or cetyl alcohol (CA) as the other, have been studied at the air-water (40% NaNP_3) interface, by means of the compression isotherms at 20℃. The experimental data have been analyzed in terms of the molecular-areas additivity rule and the two-dimensional phase rule. The polyoxyethylene-polyoxypropylene polyols are immisible with stearic acid but misible with cotyl alcohol. The polyoxypropylene glycol is immisible with both stearic acid and octyl alcohol.
