ABSTRACT

Polymer is a long chain molecule that is composed of a large number of repeating units of identical structure. Polymeric materials are used in nearly all areas of daily life and their production and fabrication are major worldwide industries. Polymers susceptible to attack by a wide variety naturally occurring and manmade agents during the period of application. Sometimes this degradation may limit the life time of the polymer and in some cases it may be desirable goal. A few factors of polymer degradation are discussed in this paper.
