ABOUT THE RESULTS OF CALCULATION OF ADSORPTION FOR LIQUID-CRYSTALLINE NANODEMULSIFIERS ON THE BASIS OF THE OXIALKYLENE BLOCK COPOLYMERS

To calculate the adsorption (Гi) of liquid-crystalline nanodemulsifiers on the basis of poly(ethylene ox-ide)–poly(propylene oxide) block copolymers on the liquid-gas interface, the Frumkin equation: Гi=Гm[1–exp(Dsi/RTГm)] was used. Correlation equations are proposed for calculating the minimum surface tension of block copolymers at maximum adsorption (Гm) depending on the molecular mas and the degree of hydroxyethylation of the corresponding oligomers, and a general adsorption isotherm in the coordinates Гi–(–Δs) is constructed and some comments, interpretations and conclusions based on the results of the research are presented
