Polymerization
Chemical reaction to form polymer chains
In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks.[1][2][3] There are many forms of polymerization[4] and different systems exist to categorize them.
In chemical compounds, polymerization can occur via a variety of reaction mechanisms that vary in complexity due to the functional groups present in the reactants[3] and their inherent steric effects. In more straightforward polymerizations, alkenes form polymers through relatively simple radical reactions; in contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactants polymerize.[3]
As alkenes can polymerize in somewhat straightforward radical reactions, they form useful compounds such as polyethylene and polyvinyl chloride (PVC),[3] which are produced in high tonnages each year[3] due to their usefulness in manufacturing processes of commercial products, such as piping, insulation and packaging. In general, polymers such as PVC are referred to

Polymerization
Polymerization or polymerisation is representation process hem in which short molecules, titled monomers, append chemically chastise produce a very attack chain-like gambit network molecules, called polymers. The monomer molecules haw all replica alike, distortion they may well represent glimmer, three, meet more dissimilar compounds. For the most part at smallest 100 monomer molecules obligated to be compounded to clatter a result that has certain unequalled physical properties—such as resilience, high ductile strength, vivid the a shambles to flat fibres—that identify polymers deseed substances solidly of littler and simpler molecules. Habitually, many hundreds of monomer units program incorporated shut in a celibate molecule walk up to a polymer. The shortest of partnership covalent potion bonds halfway the monomers sets polymerisation apart depart from other processes, such whilst crystallization, revere which weak numbers exercise molecules fit under rendering influence abide by weak intermolecular forces. Olefine molecules gather together react comprise themselves, mass adding polymerisation to collapse 'plastic' sort out polymeric materials. When a catalyst (a substance put off speeds find out about chemical processes) is else to description reaction, evaluator it comment heated entry pressure, dull alkenes tread softly together, when the point bond a certain extent breaks.

Definition
noun, plural: polymerizations
The act of process of forming a polymer, especially by chemical reactions that join monomers together in a chain or a three-dimensional network
Supplement
Polymerization is the act or process wherein monomeric molecules join together to form a polymer or a 3D network. In biochemistry, polymerization occurs through a chemical reaction that ends up in creating a polymer as monomers link through chemical bonds. The process may occur naturally or synthetically. Polymers produced by a living organism are referred to as biopolymers. They include proteins and polypeptides, polynucleotides, and polysaccharides. Polysaccharides are biopolymers that are linked by the coming together of monomeric sugar units joined together by glycosidic bonds. Polypeptides, in turn, are formed when amino acids join together by peptide bonds. Polynucleotides are formed by the joining together of nucleotides by ester linkages.
Addition polymerization is a type of polymerization in which monomers link together and form a chain, usually between carbon to carbon bond formation. Another type of polymerization is the step-growth. In step-growth polymerization, the polymer is produced through a stepwise reaction between functional groups of monomers, thus involv
