Between 1984 and 2012, IUPAC published several documents containing recommendations for the nomenclature of a wide variety of polymer types such as regular linear single-strand, irregular single strand, organic regular double-strand, and cyclic organic macromolecules, non-linear macromolecules and macromolecular assemblies, and quasi-single-strand inorganic and coordination polymers. More recently a document on source-based nomenclature for single-strand homopolymers and copolymers was published in 2016, and a document on nomenclature for dendrimers and hyperbranched polymers was published in early 2019. However, structure-based nomenclature for certain types of branched polymers with three or more blocks of identical constitutional repeating units (CRUs) (three-arm star, four-arm star or brush, etc.) has not yet been fully addressed by the IUPAC.

This document provides recommendations for structure-based nomenclature of polymers comprising a linear single strand with two or more blocks of identical CRUs and branched strands (star, comb, and brush-like) containing three or more blocks of identical CRUs connected by a central non-repeating junction unit. This document also revises some of the rules given in the document for regular linear single-strand molecules, in particular, rule 22 on polymer chains as substituents.
