La technique du Fluage Thermostimulé TSC a été appliquée à l'étude de l'évolution des propriétés anélastiques de films de polyacétylène non dopé, sous l'effet de l'isomérisation et du traitement thermique. Dans la gamme de température 77-433 K, les spectres de TSC de l'isomère trans présentent trois modes de retard respectivement situés entre 110-160 K, 270-330 K et au-dessus de 400 K. Les deux premiers modes ont deux composantes dont chacune a été résolue en processus élémentaires caractérisés par des temps de retard obéissant à une loi de compensation.The anelastic properties of undoped polyacetylene films have been followed during isomerization and thermal treatment between 77 and 433 K by the Thermostimulated Creep TSC technique. The TS...
