摘要：
The interaction between poly(N-ethyl-4-vinylpyridinium bromide) and a zwitterionic surfactant has been studied in the presence of a low-molecular-mass electrolyte, sodium bromide. Both soluble and insoluble complexes have been formed. There are two essential differences between interactions of the polycation with the zwitterionic surfactant and of polycations with anionic surfacants: interaction between the polycation and the zwitterionic surfactant may proceed only in the presence of low-molecular-mass electrolytes, while interaction between the polycation and the zwitterionic surfactant in the presence of sodium bromide may take place only at surfactant concentrations above the CMC.
