de l'évolution des propriétés anélastiques de films de polyacétylène non do-pé, sous l'effet de l'isomérisation et du traitement thermique. Dans la gam-me de température 77,-4-33 K, les spectres de TSC de l'isomère trans présen-tent trois modes de retard respectivement situés entre 110-160 K, 270-330 K et au-dessus de 4-00 K. Les deux premiers modes ont deux composantes dont cha-cune a été résolue en processus élémentaires caractérisés par des temps de retard obéissant à une loi de compensation. Abstract- 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 TSC spectra of the trans isomer...
