The simplest way to catalyze the polymerization reaction that leads to an addition polymer is to add a source of a free radical to the monomer the term free. Here the polymerization reaction initiates with ring opening of the lactam (l) as shown by reaction  therefore, it is necessary to add a small quantity of water . Polymerization reactions for the synthesis of organic polymers are often categorized into chain-growth polymerizations and step-growth polymerizations.
Polymerization chemistry is the process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. Macromolecular theory and simulations has published a special issue on the modeling and simulation of complex polymerization reactions.
The self-assembly of biomolecules, such as peptides and proteins, into filaments is conventionally understood as a nucleated polymerization.
