Abstract

The ThermoStimulated Current (TSCu) and ThermoStimulated Creep (TSCr) spectroscopies have been applied to the investigation of amorphous phases of polymeric materials. We have analysed the molecular mobility liberated at the glass transition temperature and the compensation diagram has been used for characterizing the corresponding cooperative movements. In linear polymers, the influence of chemical and physical structures has been investigated. In polymeric networks, the evolution of the structure towards chemical composition has been shown.

Zusammenfassung

Mittels TSCu- und TSCr-Spektroskopie wurden amorphe Phasen von polymeren Substanzen untersucht. Es wurde die freie molekulare Beweglichkeit bei Glasumwandlungstemperatur analysiert und das Kompensationsdiagramm zur Charakterisierung der zugehörigen kooperativen Bewegungen benutzt. Bei linearen Polymeren wurde der Einflu\ von chemischer und physikalischer Struktur untersucht. In polymeren Netzwerken konnte der Schritt von Strukturaufklärung zu chemischer Zusammensetzung gezeigt werden.
