Polymers: The word polymer derived from a greek word polymerors: poly means many and merors means parts. Hence the meaning of polymers is many parts. Polymers are usually longer than oligomers. A polymer is a compound of high molecular mass obtained by the combination of large number of small molecules i.e. monomers. They may include number of simple repeating units called monomer. The properties of monomers and polymers are different. Polymers are not volatile, and their solubility may vary depending on the structure of a monomeric unit from high to very low. Polymers are also called macromolecules because these are single, giant molecules, i.e., big size molecules.
