Complex formation between poly(vinyl ether of diethyleneglycol) and polyacrylic acid: I. Effect of low molecular salts and phenols additives

Complex formation between poly(vinyl ether of diethyleneglycol) and polyacrylic acid has been studied in aqueous solutions. The influence of non-ionic polymer nature on the complex formation ability with polycarboxylic acids and composition of complexes is discussed. The effect of low molecular salts and phenols additives on the complexation was studied. Addition of low molecular salts to solutions of starting polymers favors the complexation due to the deterioration of solvent quality. Addition of phenol molecules is unfavorable for interpolymer interactions.
