What is polymerization?

Polymerization is a chemical reaction in which small molecules called monomers join together to form a larger molecule called a polymer. This reaction occurs through the bonding of monomers, typically through covalent bonds, resulting in the formation of a long chain or network structure. Polymerization can be initiated by various methods, such as heat, light, or the presence of a catalyst. This process is essential in the production of various synthetic materials, including plastics, rubber, fibers, and adhesives.
