Standardized Polymer Nomenclature
There are multiple conventions for naming polymer substances. Many commonly used polymers, such as those found in consumer products, are referred to by a common or trivial name. The trivial name is assigned based on historical precedent or popular usage rather than a standardized naming convention. Both the American Chemical Society (ACS) and IUPAC have proposed standardized naming conventions; the ACS and IUPAC conventions are similar but not identical. Examples of the differences between the various naming conventions are given in the table below:
| Common name | ACS name | IUPAC name |
|---|---|---|
| Poly(ethylene oxide) or PEO | Poly(oxyethylene) | Poly(oxyethene) |
| Poly(ethylene terephthalate) or PET | Poly(oxy-1,2-ethanediyloxycarbonyl-1,4-phenylenecarbonyl) | Poly(oxyetheneoxyterephthaloyl) |
| Nylon 6 | Poly | Poly |
In both standardized conventions, the polymers' names are intended to reflect the monomer(s) from which they are synthesized rather than the precise nature of the repeating subunit. For example, the polymer synthesized from the simple alkene ethene is called polyethylene, retaining the -ene suffix even though the double bond is removed during the polymerization process:

Famous quotes containing the word standardized:
“Twenty or thirty years ago, in the army, we had a lot of obscure adventures, and years later we tell them at parties, and suddenly we realize that those two very difficult years of our lives have become lumped together into a few episodes that have lodged in our memory in a standardized form, and are always told in a standardized way, in the same words. But in fact that lump of memories has nothing whatsoever to do with our experience of those two years in the army and what it has made of us.”
—Václav Havel (b. 1936)
