Abstract

Bethe-Peierls approximation, as it applies to the thermodynamics of polymer melts, is reviewed. We compare the computed configurational entropy of monodisperse linear polymer melt with Monte Carlo data available in the literature. An estimation of the configurational contribution to the total liquid's C(p) is presented. We also discuss the relation between the Kauzmann paradox and polymer semiflexibility.

摘要

回顾了适用于聚合物熔体热力学的贝特-派尔斯近似。我们将单分散线性聚合物熔体计算得到的构型熵与文献中可用的蒙特卡罗数据进行了比较。给出了构型对液体总定压比热容（(C_p)）贡献的估计。我们还讨论了考兹曼悖论与聚合物半柔性之间的关系。
