Introduction to the Photo-oxidative Degradation Mechanisms of Polymers

  • Jan F. Rabek

Abstract

Polymers currently used on a large scale may be divided into three groups depending on their resistance to photodegradation (photo-oxidative degradation):
  1. (i)

    Highly photostable polymers, that are commonly used without photostabilizer added, e.g. polytetrafluoroethylene and poly (methyl methacrylates).

     
  2. (ii)

    Moderately photostable polymers that can be used without photostabilizer, e.g. poly(ethylene terephthalate) and polycarbonates.

     
  3. (iii)

    Poorly photostable polymers which need extensive stabilization for outdoor uses, e.g. polyolefins, polyvinyl chloride), poly-styrene, polyamides, polyurethanes, rubbers, coatings and cellulose.
