A comparative study of surfactant properties of aromatic macromolecular compounds of lignin and humus nature

Solutions of macromolecular compounds of lignin and humus nature were studied by the methods of surface tension and foaming. The kinetic parameters of the adsorption layer formation on the liquid-gas phase boundary were determined. In the capability to decrease the surface tension of water, the compounds of lignin and humus nature are comparable with classical low-molecular-weight surfactants.     

Hydrodynamic and surfactant properties of sulfate lignin solutions

The effect of low-molecular-weight electrolyte additions on the behavior of sulfate lignins in aqueous media was studied by capillary viscometry, tensiometry, and dynamic light scattering.     

Surfactant properties of lignosulfonates

The effect of condition of the sulfite delignification on the surfactant properties of technical lignosulfonates was estimated by the Wilhelmy method.     

Surfactant properties of kraft lignins

Formation of the adsorption layer at the solution-air interface is characterized by data on the surface tension in alkaline solutions of kraft lignins extracted from deresined spruce and birch wood. The effects of the lignin nature and solution concentration on intermolecular interaction in the surface layer are studied.     

Viscosity,sorption of water and biodegradation of starch/copolyamide blends

Compatibility of the components, shear viscosity, sorption properties in liquid and vapor water were determined for the mixture of ternary copolyamides (types 6/66/610 and 6/12/66) and amilose starch. This system was shown to be suitable for creation of biodegradable materials.
