摘要
本文采用红外、动态光散射、流变、荧光技术,研究了老化时间、模拟水矿化度、老化温度对水溶性疏水缔合聚合物本体结构和溶液性质的影响,探讨了分子组成、构象变化对分子间缠结、疏水缔合等结构的作用,建立了不同矿化度下水溶性疏水缔合聚合物溶液的温度、老化时间相关的热降解二元动力学方程。实验结果表明,疏水缔合结构的存在使其在发挥抗盐、增稠作用时能够经受一定时间的考验,老化引起的水解程度的适度增加反而有利于聚合物的增粘性。
The effect of aging time, water salinity, and aging temperature on the structure and aqueous behavior of the water-soluble hydrophobically associating polymer is investigated by FTIR, DLS, rheological and fluorescence technologies. The influence of macromolecular composition and conformation on intermolecular entanglement and hydrophobically associating are explored. For different salinities, the thermal degradation binary kinetic equation with aging time and temperature are established. The results show that after shearing, the thickening effect will rise up in a certain time, due to the hydrophobically associating structure. And the thickening property is enhanced by moderate increase of hydrolysis level caused by aging effect.
