摘要：
Fluorescent spectroscopy is used to investigate the processes of intermolecular association in mixed solutions of polymethacrylic acid (PMAA) and anionic sodium dodecylbenzenesulfonate (SDBS). We propose a model for describing the stage-by-stage mechanism of association processes and conclude that the nature of intermolecular associates depends on the PMAA-SDBS concentration ratio in the solution. Studying the kinetics of fluorescence decay reveals the simultaneous existence of two types of formations capable of pyrene solubilization.
