摘要：
The complexation of homo- and copolymers of vinyl ether of monoethanolamine with poly,(acrylic acid) has been studied in aqueous solutions. The effect of pH on the complexation has been shown. In acidic media (pH 2.4). the polyelectrolyte complex is enriched by anionic polymer units. In weakly acidic media (pH 4-6). the formation of stoichiometric polyelectrolyte complex is observed. In higher pH media (pH 6-8), the polycomplex contains an excessive amount of cationic polymer. The stability of the polyelectrolyte complexes is affected by the addition of inorganic salts and dimethylformamide.
