According to mechanical data it might be concluded that the thermooxidative degradation of PET is described by a single first order process. Due to the thickness of the sample and as the degradation temperatures were above T/sub A/, the thermooxidative degradation process is homogeneous. Thermal analysis have revealed the presence of a weak liquid-liquid transition. Both the liquid-liquid transition and the glass transition depends on degradation time and temperature. From the effect of the thermooxidative degradation on T/sub G/, it is possible to conclude that at low degradation temperatures the polymer crosslinks. At 150/spl deg/C, a transition from crosslinking to chain scissions at large degradation times (above 500 h) is noticed. Hence T/sub c/ depends on the degradation time and temperature. Dc electrical conduction measurements have revealed two competing first order relaxation processes, ascribed to crystalline and amorphous domains. Further studies are in course, in order to elucidate this behaviour.","PeriodicalId":13148,"journal":{"name":"ICSD'98.

The capability of the measurement system has been checked by showing, in atmospheric air, the transition from the ohmic regime to the saturation regime, and by demonstrating that in the nonpolar liquid cyclohexane the ohmic regime takes place, as expected, in the range 0.1 s to 100 s. Measurements on commercial capacitors, using widely different insulating materials, and on polymer thick sheets have shown that perfectly reproducible results can be easily and quickly obtained. The new method has the special merit of overcoming the major inconvenience of the usual (and standardized) method of measurement of insulation resistance which is greatly affected by previous conditioning treatment.","PeriodicalId":13148,"journal":{"name":"ICSD'98.
