Abstract
The pairs of sugars glucose-fructose and fructose-sucrose have been comelted and quenched to form binary glasses. Glass-to-rubber transition temperatures
T
g
and heat capacities of the glasses and the crystalline sugars have been measured by computer-aided differential scanning calorimetry.
T
g
was found to vary smoothly with glass composition and the (constant pressure) heat capacities
C
of the glasses and rubbers varied monotonically with
T
g
. It is suggested that
C
is a better and experimentally more convenient indicator of
T
g
and the glassy state than is the inferred viscosity in terms of which
T
g
is usually defined. The
T
g
data for mixtures extrapolate smoothly to a
T
g
of fructose of 286 K which differs substantially from the value (373 K) previously reported.
C
values for the crystalline sugars agree with literature data.
