title: pH effects in the formation of interpolymer complexes between poly(N-vinylpyrrolidone) and poly(acrylic acid) in aqueous solutions.
abstract: The critical pH values for hydrogen-bonded interpolymer complexes of poly(N-vinylpyrrolidone) and poly(acrylic acid) in aqueous solutions were determined. The effect of polymer concentrations, molecular weights and addition of inorganic salts (NaCl and KCl) on the complexation was studied.
