摘要：

An equation of state, previously reported, was used to calculate the volume dependence of the isothermal bulk modulus of polymers. The principal results are as follows: (1) The isothermal bulk modulus can be expressed as a function of volume and temperature. (2) The ratio of the entropic contribution to the total value of the bulk modulus, denoted ΥS, depends only on temperature and not on pressure. (3) For polymer melts, ΥS is negative. (4) For polymer solids, the absolute value of ΥS is less than unity. If the bulk modulus can be approximated as a function of volume only, then ΥS can be ignored.
