Polymer is a standout amongst the most imperative classes of non-metallic materials. Different sorts of polymeric materials happen in wealth as normal items. Proteins, starches and shellac are a few illustrations. Proteinaceous fiber (fleece, silk) and starch filaments (cotton, flax) have been being used for a very long time. Early endeavors to enlarge the application regions of polymers were for the most part kept to artificially adjusting the characteristic materials. Change of casein by formaldehyde, esterification of cellulose also, vulcanization of regular elastic are a few cases of the improvement of something beyond valuable items from normally happening polymeric materials. Contingent upon the application, the perfect lifetime of a polymeric item could shift from weeks to years. The security and toughness of polymeric materials amid thermo-or photograph oxidation or under other outer impacts is of outmost significance in applications, for example, coatings, building materials, and car parts, though a quickly degradable material is ideal in transitory brief time applications. There are impressive monetary and ecological advantages in the event that we can outline polymers for short or long lifetimes and also keep the arrival of hurtful substances from the materials amid their lifetime.
