Viscosity and molecular behaviour of narrow polyoxyethylene fractions in melt

Solvation effect upon glass transition temperature and conductivity of poly(ethylene oxide) complexed with alkali thiocyanates

“…well as T" = (Tg -26) ± 2 close to the present T" value, were quoted as the best VTF parameters for the PEO viscosity data in the temperature range 70-140 °C. 24 It thus appears that the temperature dependence of for the present electrolytes is identical with that of for pure PEO. Therefore, it is the assumed temperature-independent preexponential factor A in eq 3 that mainly accounts for the change of conductivity associated with either the nature of the salt or its concentration in the system.…”
