SOURCE-BASED NOMENCLATURE FOR NONLINEAR MACROMOLECULES AND MACROMOLECULAR ASSEMBLIES

A source-based nomenclature for non-linear macromolecules and macromol ecular assemblies is proposed. Source-based or structure-based names f or linear regular (single-strand and double-strand) and irregular macr omolecules can be derived using rules published previously. In contras t, the present document deals with the source-based naming of non-line ar macromolecules and assemblies of macromolecules. The former compris e branched, graft, comb, star, cyclic and network macromolecules; the latter comprise polymer blends, interpenetrating polymer networks and polymer-polymer complexes. The names of non-linear macromolecules are formed by citing source-based name(s) of the constituent linear chains (s) and denoting their mode(s) of combination by prefixes and connecti ves. Specification of molecular weight, composition or branch-point fu nctionality(ies) of the macromolecule or its constituents may be given in parentheses.
