Abstract

In this paper, the f(alpha) conversion functions for random scission mechanisms have been proposed to allow for the construction of generalized master plots suitable for these kinds of mechanisms. The master plots have been validated by their application to simulated data and to the thermal degradation of poly(butylene terephthalate), polyethylene, and poly(tetrafluoroethylene).

摘要

本文提出了用于随机断裂机制的 f(alpha)转换函数，以便构建适用于这些机制的广义主图。通过将主图应用于模拟数据以及聚对苯二甲酸丁二醇酯、聚乙烯和聚四氟乙烯的热降解，验证了这些主图的有效性。
