values showed that the polymerizable surfactant solutions had limited stability. The hydrolysis stability and solubility of the polymerizable surfactant were also investigated. The solubility results have shown that it was soluble in polar solvents while insoluble in nonpolar solvents both at room temperature and 40 °C. The acidic and basic hydrolysis of the surfactant increased as the temperature increased
N-羟甲基丙烯酰胺采用两步法合成了一种新型的具有反应性乙烯基的可聚合非离子表面活性剂。表面活性剂分子的结构通过傅里叶变换红外光谱1H核磁共振和质谱。通过表面张力,电导率和荧光光谱测量研究了表面活性性质及其自组装性质。与其他非离子表面活性剂相比,这项研究表明,这种可聚合表面活性剂在临界胶束浓度下具有较高的临界胶束浓度(CMC)值和表面张力值。所获得的CMC值在测量之间是兼容的。0.02–0.038M。Zeta电势测量也提供了胶束形成的证据,并且获得的Zeta电势值表明可聚合表面活性剂溶液的稳定性有限。还研究了可聚合表面活性剂的水解稳定性和溶解性。溶解度结果表明,它在室温和40°C下都可溶于极性溶剂,而不溶于非极性溶剂。表面活性剂的酸性和碱性水解随着温度的升高而增加,在80°C下的水解稳定性为180分钟(碱性介质)和55分钟(酸性介质)。
