Abstract:

Bulk compressibilities of a series of crosslinked polymers have been measured at pressures up to 10,000 atmospheres and over the temperature range of 25 to 250 C. These polymers exhibited non-linear compressibility characteristics reaching a maximum compressibility of about 15 at 10,000 atmospheres and decreasing with increasing pressure. By conducting the measurements at slow speeds, data were obtained which could be expressed as glass-rubber phase diagrams. The nature of the observed compressibilities is discussed and the variation of the glass transition with pressure is analyzed on the basis of Ehrenfest thermodynamics. Author
