A brief guide to polymer nomenclature
Résumé
Polymer nomenclature applies to idealized representations where minor structural irregularities are ignored. A polymer can be named in one of two ways, such as source-based nomenclature can be used when the monomer can be identified. More explicit structure-based nomenclature can be used when the polymer structure is proven. A homopolymer is named using the name of the real or assumed monomer from which it is derived, such as poly(methyl methacrylate). Monomers can be named using IUPAC recommendations or well-established traditional names. Structure-based nomenclature uses that of the preferred constitutional repeating unit (CRU) in place of the monomer name used in source-based nomenclature. It is determined when a large enough part of the polymer chain is drawn to show the structural repetition, while the next step involves identifying the subunits that make up each of these structures.
