Polymerization | Definition, Classes, & Examples | Britannica
Polymerization, any process in which small molecules known as monomers combine chemically to produce a very large chainlike or network molecule, called a polymer. Usually at least 100 monomers must be combined to make a product that has certain unique physical properties.

Polymerization reactions involve three basic steps: initiation, propagation, and termination. An initiation reaction must occur to functionalize a monomer unit before the reaction can begin. Once a monomer has been functionalized, another monomer unit can bind to it, and the functionalized carbon center propagates to the new monomer unit.
The chain of production of polymers requires expert knowledge in different areas: (i) polymer synthesis, both from the chemistry and the engineering aspects; (ii) poly-mer characterization, including chemical, physicochemical, rheological properties and others; and (iii) polymer process-ing and transformation into final products.
Polymer Processing - an overview | ScienceDirect Topics
The aim of polymer processing is to convert the polymer, usually in the form of powder or granules, into a more useful form. Usually the change involved is largely physical, although in some conversion processes chemical reactions play a part.
Polymerization - an overview | ScienceDirect Topics
Polymerization, in polymer chemistry, is the process of reacting monomer molecules together in a chemical reaction to form three-dimensional networks or polymer chains.
