摘要： 针对疏水缔合聚合物AP-P4的溶解特性，通过显微镜观察法和胶体称重法定性定量研究了AP-P4的溶胀和溶解过程，分析了注入水中主要金属离子、水处理剂以及温度对AP-P4溶解性的影响。结果表明，AP-P4在水中的溶解速度主要由聚合物溶胀团块表面分子的溶出扩散速度控制；低质量浓度的Na+、Ca2+、Mg2+或SDBS对AP-P4溶解性影响不大，溶液中存在少量的Fe3+或OP-10会显著改变AP-P4的溶解性；适当提高温度能够促进AP-P4的溶解。

Abstract: he swelling and dissolution process of AP-P4 was studied qualitatively and quantitatively by means of microscope observation method and colloid weighing method, and the effects of main metal ions, residual reagent and temperature on the solubility of AP-P4 in were analyzed, which were against dissolution characteristics of hydrophobically associating polymer AP-P4. The results showed that the dissolution rate of AP-P4 in water was mainly controlled by the swelling velocity of polymer swelling and the dissolution and diffusion rate of the surface molecules. The low mass concentrations of Na+, Ca2+, Mg2+ or SDBS had little effect on the solubility of AP-P4, and a small amount of Fe3+ or OP-10 in the solution could significantly alter the solubility of AP-P4. Increasing the temperature properly could promote the dissolution of AP-P4.
