polymerization Definition, Classes, & Examples Britannica

Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer.The monomer molecules may be all alike, or they may represent two, three, or more different compounds.Usually at least 100 monomer molecules must be combined to make a product that has certain unique physical properties Chemical Reactor for Vinyl Acrilic PolimerizationViolent Self-Polymerization Reactions - AristaTekVinyl acetate, UN1301, is another chemical that can undergo bulk polymerization in storage vessels. This polymerization is extremely violent and may generate a pressure surge of over 40 atmospheres due to the monomer vapor pressure, enough to explode the vessel. The polymerization may be initiated by exposure to small amounts of peroxide;Vinyl acetate C4H6O2 - PubChemVinyl acetate is an industrial chemical that is produced in large amounts in the United States. It is a clear, colorless liquid with a sweet, fruity smell. It is very flammable and may be ignited by heat, sparks, or flames. Vinyl acetate is used to make other industrial chemicals.
