| Abstract: | Viscosity properties of dilute and concentrated ethanol solutions of blends of ethyl cellulose with polyvinylpyrrolidone and Poviargol bactericidal formulation (silver metal nanoparticles stabilized with polyvinylpyrrolidone) were studied. The physicomechanical and thermomechanical properties of films prepared from solutions of the polymer blends were determined. Experiments on solvent vapor sorption showed that ethyl cellulose is incompatible with polyvinylpyrrolidone and Poviargol in the solid state in the entire composition range examined. |
