Notizen:
The hydrodynamic properties of dilute solutions of poly(N-viny1-2-pyrrolidone) (PVP) and its Co(II) complexes were studied by high-speed sedimentation and viscosimetry methods. Unperturbed dimensions of PVP in two solvents (ethyl alcohol and water) and those of PVP complexes with the cobalt ions in water were determined. Unperturbed dimensions of PVP coils were shown to be dependent on the solvent nature, and those of polymer-metal complexes on metal concentration.
