Abstract

The densification of polymethyl methacrylate resulting from pressure and temperature treatment in a Bridgman anvil device has been studied at temperatures to 245 C and pressures to 50 kbar. Effects of treatment in the glass transition region, in the glassy state, and on samples held in the transition region under pressure and then vitrified by rapid application of a high pressure, are studied. The results are compared with thermodynamic theories of the glass transition and with similar data on other polymers and inorganic glasses.
