Abstract
The effect of the structure of the reacting compounds and reaction conditions on the composition of polyelectrolyte complexes formed in the reaction of polyanions — graft copolymer of cellulose and polyacrylic acid and polymethacrylic acid sodium salt (C-gr-PAa (PMAA)) and polyhexamethyleneguanidine hydrochloride (PHMG) and polyethylenimine (PEI) — and the kinetics of their formation were investigated. The conditions that ensure complete binding of the polycation were determined and the necessity of a significant excess of polycation and long duration of the reaction for formation of complexes of stoichiometric composition was demonstrated. In studying desorption of antimicrobial substances from the polyelectrolyte complex, the effect of the process production scheme and type of cation and the significant role of diffusion factors in this process on the stability of the complex was established.
