polymerization reactions

Any process called polymerization involves the chemical combination of relatively tiny molecules, known as monomers, to create a very big chainlike or network molecule, known as a polymer. The monomer molecules could all be the same or could stand in for two, three, or more distinct compounds. In order to create a product with particular distinctive physical features, such as elasticity, high tensile strength, or the capacity to form fibers, at least 100 monomer molecules must typically be mixed; frequently, thousands of monomer units are merged into a single polymer molecule.

Typically, two types of polymerization are differentiated. Each stage of condensation polymerization is accompanied by the creation of a molecule of some simple chemical, frequently water. In contrast to polymerization, which results in the production of byproducts, monomers react to create polymers. Typically, addition polymerizations take place in the presence of catalysts, which occasionally exercise control over structural elements that significantly affect the polymer's characteristics.
