heal.abstract	The dielectric properties of poly(ethylene oxide) (PEG) are studied by dielectric relaxation spectroscopy measurements in wide ranges of frequency (5-2x10(9) Hz) and temperature (193 - 300 K). PEO/water systems are also studied in a wide range of water content h (0 - 0.85 grams of water per grams of dry PEG). The measurements allow to distinguish between the dipolar secondary mechanism gamma and effects related to free charge motion. The data are analyzed within the formalisms of permittivity, epsilon, and electric modulus, M. The water has been found to plasticize the dipolar process and to affect strongly the conduction process. A critical water content he, he = 0.13, has been found for the mechanism of charge transport.	en
