The interaction of poly (n-vinyl-pyrrolidone) (PVP) having M_ω=8.8×10~4 with alcohols was investigated by means of laser light scattering. A comparison of the results with those of viscosimetry was made. It was found that addition of denaturing agent guanidine chloride (GC) into the studied systems leads to a higher apparent molecular weight
a lower hydrodynamic radius and [η] owing to the formation of complex PVP-GC
and causes marked changes in second Virial coefficient
second diffusion virial coefficient and Huggins constant.
