十六烷基三甲基溴化铵-聚（乙烯亚胺）-水体系在膦酸酯水解反应中的催化作用（速率常数增加三个数量级）是由于聚合物-胶体复合物中反应物的浓度及其微环境的变化。催化剂的效率取决于底物、表面活性剂和聚合物的结构。
The catalytic effect of the cetyltrimethylammonium bromide–poly(ethylenimine)–water system in the hydrolysis reactions of phosphonic acid esters (an increase in the rate constant by three orders of magnitude) is due to the concentration of reactants in polymer–colloid complexes and changes in their microenvironments. The catalyst efficiency depends on the structures of substrates, surfactants, and polymers.
