Polymers are used widely in our day-to-day life. They fulfil the requirements of strength, elasticity, insulation, and so on. Polymers have always come up with the promising compounds that helped shape the needs of the livelihoods of mankind. Polymers are large heavy molecules which are formed by joining the units of monomers together by characteristic bonds.
