Abstract : Bulk compressibilities of a series of linear and crosslinked polymers have been measured at pressures up to 20,000 atmospheres and over the temperature range 22 to 200C. These polymers exhibited non-linear compressibility characteristics reaching a maximum magnitude of the compressibility of about 20% at 20,000 atmospheres. In this report the nature of the observed compressibilities are discussed and glass-rubber phase diagrams are given for several systems. It is shown that the compressibility of polystyrene is time dependent. (Author)
