surfactants. Two different reaction methods were used; either unsaturated alcohols or bromine-containing alcohols were applied as starting compounds for the preparation of the organophosphorous surfactants. The self-aggregation and micelle formation of the prepared compounds were investigated in aqueous solution by dynamic light scattering measurements. The critical micelle concentration of the P-containing
摘要合成了可聚合的两亲有机磷化合物,研究了它们的自聚集行为。所研究的分子包含一个亲水性的磷端基,一个长度可变的3至11 CH 2烷基链间隔基基团和在另一链端的可聚合甲基丙烯酸基团。因此,分子代表一类可聚合表面活性剂。使用了两种不同的反应方法。不饱和醇或含溴的醇都可以用作制备有机磷表面活性剂的起始化合物。通过动态光散射测量研究了在水溶液中制备的化合物的自聚集和胶束形成。在所有情况下,含P两亲物的临界胶束浓度均小于0.040 mol / l,并强烈取决于磷头部基团的极性和间隔基的链长。 图形概要 提出了有机磷两亲物作为用于改性金属氧化物表面的表面活性单体的合成。磷头基和甲基丙烯酸酯基之间的间隔物就其长度和组成而言是变化的。研究了这些甲基丙烯酸酯官能化的磷酸盐和膦酸酯表面活性剂的自聚集行为。
