Polymerization Definition Classes Examples Britannica

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. Polymer, any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, that are multiples of simpler chemical units called monomers. polymers make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids. moreover, they constitute the basis of such.

Polymerization Definition Classes Examples Britannica Polyethylene. cellulose acetate. nitrocellulose. pvc. silicone. major industrial polymers, chemical compounds used in the manufacture of synthetic industrial materials. in the commercial production of plastics, elastomers, man made fibres, adhesives, and surface coatings, a tremendous variety of polymers are used. Polymers are large molecules made of small, repeating molecular building blocks called monomers. the process by which monomers link together to form a molecule of a relatively high molecular mass is known as polymerization. polymers make up many of the materials in living organisms. proteins are polymers of amino acids, cellulose is a polymer. Polymerization is a chemical reaction that involves the formation of long chain molecules known as polymers from smaller units called monomers. polymerization reaction occurs when multiple monomers chemically bond together, forming large, complex structures. the polymerization process can be either natural or artificial. An example is the equimolar copolymer of styrene and maleic anhydride formed by free radical chain growth polymerization. [39] a step growth copolymer such as nylon 66 can also be considered a strictly alternating copolymer of diamine and diacid residues, but is often described as a homopolymer with the dimeric residue of one amine and one acid.

Summary. polymers are large molecules made up of many atoms linked together by covalent bonds. they usually contain carbon and often other atoms such as hydrogen, oxygen, nitrogen, halogens and so forth. thus they are typically molecules considered to be in the province of organic chemistry. implicit in the definition of a polymer is the. The class of acrylic fibers is made from polymers of acrylonitrile. the first of these, with the trade name orlon, was introduced in the united states in the 1940s. of all man made fibers, the acrylics resemble wool most closely. they are used alone or blended with wool for sweaters, socks, blankets, and carpets.
