| Abstract: | Internal pressures (Pi) have been measured at low external pressure for solid poly(ethylene oxide) 6000 and solid poly(ethylene oxide) 6000 swollen with 5% by weight liquid poly(ethylene oxide) 200. Values of Pi are low (Pi < 108 Pa at 10°). The effect of swelling with liquid, which is located exclusively within the disordered layers of the solid, is that expected on the basis of additivity. |
