POLYMOLECULAR CHARACTERISTICS OF SODIUM LIGNOSULFONATE, CHITOZANE AND POLYETHYLENPOLYAMINE
The hydrodynamic, molecular and conformational properties of sodium lignosulfonate, chitozane and polyethylenpolyamine in solutions have been studied by viscosimetry, laser correlation spectroscopy and ultracentrifuga-tion methods. Conformational properties of sodium lignosulfonates macromolecules are determined by presence of the charged groups and branching. On parameters of thermodynamic flexibility of sodium lignosulfonates macromolecules belong to polymers with a hard chain. Chitozane macromolecules were shown to be simulated by partially permeable persistent chain and belong to polymers with hard chain. Features of hydrodynamic behaviour of polyethylenpolyamine macromolecules in solution allow relating polyethylenpolyamine to linear flexible chain polymers with very weak intermolecular interaction.
