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.
polymer degradation, polystyrene, polyethelene, thermoplastics,
addition polymers, condensation polymers,nylon-6,6,adipic acid, hexamethylene, thermal
degradation, mechano degradation, oxidative and UV degradation, hydrolysis, radiolysis.
