摘要：
The formation of polylectrolyte complexes (PECs) by the interaction between poly(dimethyldiallylammonium chloride) and native potato starch was investigated. PECs with optimal dye binding properties containing 0.015-0.02 mole cationic polymer/anhydroglucose residue were prepared. It was shown that the anionic (acid) dye was incorporated into PECs by electrostatic interaction with the free cationic groups of PECs. The principal role of the hydrophobicity of the PECs containing acid dye in their stability in water solutions was revealed. The precipitation occurred due to the minimum amount of free ionic groups.
