AI Article Synopsis

  • The paper aims to create a volume function (W) for polymer glasses and determine their volume based on compactivity (X) using a statistical-mechanical approach tailored for semiflexible polymers.
  • It highlights the relevance of statistical mechanics and entropy concepts in understanding the behavior of polymer glasses.
  • The research draws parallels between polymer glasses and "tapping" experiments commonly used for powders to validate its methodology.

Article Abstract

The purpose of the present paper is to propose an idea to construct the volume function W for polymer glasses and calculate the volume of polymer glasses as a function of the compactivity X utilizing a statistical-mechanical method developed for semiflexible polymers. We also discuss the analogue for glasses of "tapping" experiments which show the validity of statistical mechanics and the entropy concept in powders.
