摘要：
The influence of MoCl5 on the conformation and morphology of poly(N-vinyl-2-pyrrolidone) (PVP) was examined in this study. Viscometric, densimetric, solubility, and scanning electron microscopy techniques were carried out. A conformational transition at 75 mM of MoCl5 and so a more compact conformation of PVP was observed. A preferential exclusion of salt from the inside the polymer structure and a preferential adsorption of water was produced. A salting-in behavior was exhibited at all concentrations studied, the binary mixture being thermodynamically unfavourable. Scanning electron microscopy shows changes on polymer structure due to its interaction with the salt, MoCl5 being a nucleating agent for PVP.
