Definition of Polymerization



The condensation process in which the small molecules known as monomers tend to link with each other and form larger molecules, polymers, is termed as polymerization. This is a chemical process in which huge molecules that are in the form of a chain and network are formed. The monomers which form polymers may be of the same kind or may be different.

 


Sometimes, more than 3 types of different compounds join together to form polymers. The physical properties like elasticity, tensile strength are acquired by those polymers which are composed of more than hundred monomeric units. Generally, thousands of monomers link with each other through stable covalent bonds to form a good polymer molecule.

 


Examples of Polymerization:

The carbohydrates like cellulose, starch, glycogen, etc. are formed by the condensation of glucose residues. PVC, PVA, polyesters etc. all are polymers.
