A. Cournoyer et L. Bertrand, PHOTOTHERMAL SPECTROMETRY OF THERMODYNAMICAL PROPERTIES IN THE VICINITY OF THE GLASS-TRANSITION OF POLYMERS, Progress in Natural Science, 6, 1996, pp. 265-268
We demonstrate the interest of the simultaneous use of constrained pho
todeformation (CPD) and thermal lensing (TL) ina one-dimensional geome
try in order to obtain independent quantitative measurements of the th
ermodynamical properties in the vicinity of the glass transition of po
lymers.
