Abstract :
The polyetherimide is an amorphous thermoplastic resin with a high glass transition temperature. It is characterised by high heat resistance and mechanical properties which make it suitable for industrial application. Two different polyetherimide (varying by the chemical formula) are investigated here, in term of their space charge behaviour. The comparison reveals important variations in the electric properties
