    A brief guide to polymerization terminology (IUPAC Technical Report)
    Luscombe, Christine K.; Moad, Graeme; Hiorns, Roger C.; Jones, Richard G.; Keddie, Daniel J.; Matson, John B.; Merna, Jan; Nakano, Tamaki; Russell, Gregory T.; Topham, Paul D. (Walter De Gruyter, 2022-08)
    The use of self-consistent terminology to describe polymerizations is important for litigation, patents, research and education. Imprecision in these areas can be both costly and confusing. To address this situation the International Union of Pure and Applied Chemistry (IUPAC) has made recommendations, which are summarized below. In the version shown as the supplementary material, references and hyperlinks lead to source documents; screen tips contain definitions published in IUPAC recommendations. More details can also be found in the IUPAC Purple Book. This guide is one of a series on terminology and nomenclature. Refer to the supplementary material for the complete and interactive version of this brief guide.

    Terminology for chain polymerization (IUPAC Recommendations 2021)
    Fellows, Christopher M.; Jones, Richard G.; Keddie, Daniel J.; Luscombe, Christine K.; Matson, John B.; Matyjaszewski, Krzysztof; Merna, Jan; Moad, Graeme; Nakano, Tamaki; Penczek, Stanislaw; Russell, Gregory T.; Topham, Paul D. (Walter De Gruyter, 2022-09)
    Chain polymerizations are defined as chain reactions where the propagation steps occur by reaction between monomer(s) and active site(s) on the polymer chains with regeneration of the active site(s) at each step. Many forms of chain polymerization can be distinguished according to the mechanism of the propagation step (e.g., cyclopolymerization - when rings are formed, condensative chain polymerization - when propagation is a condensation reaction, group-transfer polymerization, polyinsertion, ring-opening polymerization - when rings are opened), whether they involve a termination step or not (e.g., living polymerization - when termination is absent, reversible-deactivation polymerization), whether a transfer step is involved (e.g., degenerative-transfer polymerization), and the type of chain carrier or active site (e.g., radical, ion, electrophile, nucleophile, coordination complex). The objective of this document is to provide a language for describing chain polymerizations that is both readily understandable and self-consistent, and which covers recent developments in this rapidly evolving field.
