Polymerization refers to the procedure of reacting molecules of monomers together in a chemical reaction to produce polymer chains or three-dimensional networks.
In the chemical compounds, polymerization takes place through numerous reaction mechanisms, which change in complexity due to functional groups present in reacting compounds, and their inherent steric effects.
At the time of polymerization, the additional internal bonds of the monomer will break and amalgamate with other monomers, producing the repeating chain.
