Thermo-oxidative Degradation of Polymers
T. R. Crompton
The oxidative and thermal degradation of polymers has very important implications on their suitability for
particular end-user applications. Particularly in relation to their physical properties and the lifetime over which the
manufactured article retains these properties, after which they become unsuitable for purpose.

This book brings together information on the thermooxidative resistance of polymers to change during processing
and end-use life.
Our present understanding of the chemical changes of the polymer that accompany degradation are also reviewed
and the analytical methods by which changes can be ascertained are also discussed.
The principle techniques used in thermooxidative studies are based on thermal analysis methods such as
thermogravimetric analysis and differential scanning calorimetry and on methods based on polymer pyrolysis
followed by gas chromatography and mass spectrometry and/or infrared spectroscopy of the volatiles produced.
Other techniques which have have been include nuclear magnetic spectroscopy, electron spin resonance spectroscopy
and methods based on chemiluminescence and positron annihilation lifetime mass spectrometry.
This book will be of interest to those involved in the investigation of polymer stability and studies of the mechanics
of polymer degradation, to polymer manufacturers and those who use polymers to manufacture end-use articles.
The book will also be of interest to those involved in the manufacture of stabilisers for oxidation resistance
for use in polymer manufacture, mechanical engineers and designers of polymer products.
