Polyelectrolyte complexes based on Na-carboxymethylcellulose and polyethyleneimine chloride: identification and structure.

By using X-ray structural analysis of polyelectrolyte complexes based on of strong anionic and cationic polyelectrolyte were investigated. By using FTIR and differential scanning calorymetry this polymer system were identificated. It was esteblished what by molar ratio 1:2 of anionic and cationic polyelectrolyte stochiometric compoun realized. For this compound maximal change axes of microheterogeneous structure of complexes realized. It was esteblished what by major concentration of cationic polyelectrolyte cristalline structure of complexes realized. [ABSTRACT FROM AUTHOR]
