Positron lifetime measurements were carried out in a series of poly(ethylene oxide)-PEO-of different average molecular weights (M w ): 1000, 1500, 6000, 10,000, 300,000, and 4 M. The mean radius (R ) and the mean free volume size (V f ) values were determined using a semiempirical equation that corr
