The reliability of kinetic analysis of the thermal degradation of polymers

Polymers are very important materials in modern society with applications in almost every aspect of our way of life. Their structures, i.e. properties can be altered and tailored to produce materials with a broad range of thermal, mechanical, optical, barrier and various other properties. Being mostly organically based, it is very often the case that thermal properties and thermal degradation are the limiting factors for their final application. This makes the investigation of thermal properties, thermal degradation and kinetic analysis of thermal degradation of polymers very important and challenging. In general, practical purpose of kinetic analysis of the thermal degradation of polymers is the prediction of their process rates and lifetimes, while theoretical purpose includes the interpretation of experimentally determined kinetic triplets. In order to use the results of kinetic analysis for both practical and theoretical purposes, the reliability of kinetic analysis of the thermal degradation of polymers must be accomplished. The purpose of this lecture is to discuss some factors that can possibly influence the results of the kinetic analysis but which might be easily overlooked.
