“…3, there is a kink in the linear form of the dependence of the hydrodynamic radius R of neonols on the number of oxyethylene groups in the molecules of neonols. The previously performed estimates of the hydrodynamic radii of molecules in pure neonols [17] agree well with the values obtained. Dynamic changes in the structure of oxyethylene chains of neonol molecules illustrate the models generated by the HyperChem software, Fig.…”

“…The phenomenon of contraction in neonols is observed [16] under the condition n ≥ 9. Previously [17], we measured the diffusion coefficients of molecules in pure neonols AF9-n at various temperatures by NMR diffusometry. We showed that the linear dependence of the diffusion coefficients and activation energies of the translational motion of molecules of pure neonols on the number n changes slope at n ≈ 9, confirming the presence of a contraction phenomenon.…”

“…The dynamic and structural properties of aqueous solutions of neonols were studied in detail by us earlier. Relations were obtained expressing the dependence of the cloud point on the number of oxyethylene groups in neonol molecules at a constant concentration of neonols in solutions with C = 1 wt %. The hydration of oxyethylene chains was studied and it was shown that ∼3 to 4 water molecules bound to one oxyethylene group.…”
