Influencing of saltiness of water on formation waterinsoluble and watersoluble polyelectrolyte complexes
Phase changes in aqueous and water-salt solutions of polyelectrolyte complexes (PEC) - resultants of reaction between sodium lignosulphonates (LSNa) and chitosan (Ch), LSNa and polyethylenpolyamine (PEPA) have been investigated. High responsiveness of LSNa-Ch (PEPA) to change of ionic strength of solution and рН was scored. Influencing of molecular mass LSNa on formation of PEC is installed. During complex formation of oligomeric fractions LSNa in the system LSNa-PEPA, polyelectrolyte complexes are not being formed, in acid solutions sodium chloride adding prevents complex formation.
