Explanation
Polymerization is a reaction in which two or more molecules of the same kind join together to form a large molecule of higher molecular mass. The molecules participating in polymerization are called monomers, and the product is called a polymer. Natural rubber is the polymer of isoprene. Isoprene is an organic compound with the formula. $CH_2 = C(CH_3) - CH = CH_2$.
