NATURAL AND SYNTHETIC POLYMERS
A polymer (Poly means many and mer means parts) is a large but a single chain-like molecule in which the repeating units derived from small molecules called monomers are bound together. The process by which monomers are transformed into a polymer is called polymerization. ...
