Effect of hydrostatic pressure on certain thermodynamic properties of polymeric materials

  • Published:
Polymer Mechanics Aims and scope

Abstract

By means of a thermodynamic approach it is demonstrated that the mechanical properties of homogenous polymeric materials depend only on specific volume. Expressions are derived for the entropy and volume coefficient of thermal expansion as functions of hydrostatic pressure and temperature. It is shown that for both crystalline and amorphous polymeric materials the bulk modulus depends on reduced temperature.
