Abstract
Mechanical and optical characterization of Hysol 4290 as a function of time and temperature is presented. The kinetic theory of polymers, the Williams, Landel and Ferry equation and the time-temperature superposition principle, is discussed. Rubber-like elasticity is used as a simple experimental method to ascertain if the time-temperature superposition should be expected to apply. Finally, the glass-transition temperature of Hysol 4290 is established and its importance in correctly assessing experimental data is discussed.
