Figures

Image of FIG. 1.
FIG. 1.

(a) The BSW fits along with the dynamic data for m-toluidine from 186.2 to 192.2 K. The red lines are the BSW fits. [Data from Hutcheson and McKenna (Ref. 11).] (b) The BSW fits along with the dynamic data for sucrose benzoate from 335.2 to 347.2 K. The red lines are the BSW fits. [Data from Hutcheson and McKenna (Ref. 11).]

FIG. 2.

(a) KWW fits to the relaxation data of m-toluidine from 186.2 to 192.2 K. The red lines are the KWW fits. [Data from Hutcheson and McKenna (Ref. 11).] (b) The KWW fits to the relaxation data of sucrose benzoate from 335.2 to 347.2 K. The red lines are the KWW fits. [Data from Hutcheson and McKenna (Ref. 11).] (Remark: The data obtained below the nominal T g were for samples aged into equilibrium before testing.)

Image of FIG. 3.
FIG. 3.

The glassy modulus dependence on temperature for (a) m-toluidine, (b) sucrose benzoate. (Lines, except for BSW data for the m-toluidine, represent KWW, linear fit, and BSW, linear fit, as indicated in figures.)

Image of FIG. 4.
FIG. 4.

ln(η) vs G (T)/K B T for different small molecule glass formers. The red lines and the blue lines are the Dyre model [Eq. (9)] fits. Fit parameters are given in the figures. (a) m-toluidine, (b) sucrose benzoate.

Image of FIG. 5.
FIG. 5.

Temperature shift factors and dynamic viscosity for (a) m-toluidine and (b) sucrose benzoate. The dynamic viscosity data are vertically shifted by an arbitrary constant A to make the curves overlay. The green line represents the Dyre shoving model fit to the dynamic viscosity data and the stress relaxation a T . The red line represents the VFT fit to the dynamic viscosity and the stress relaxation a T . For m-toluidine, A = −8.7; for sucrose benzoate, A = –9.67.

Image of FIG. 6.
FIG. 6.

Logarithm of the viscosity (a) as function of T g /T and (b) as function of the variable x(x = G (T)T g /G (T g )T).
