Summary
Ultracentrifugal studies were made on poly/1-vinyl-2-pyrrolidone-co-maleic acid/ samples eliminating the polyelectrolyte character of the polyacid. Molecular weight values were evaluated from sedimentation-diffusion equilibrium measurements. Good correlation was found between weight average molecular weight values obtained from the equilibrium measurements and those evaluated viscometrically, applying the Mark-Houwink equation determined earlier.
