A. INTRODUCTIONMacromolecular (polymer) nomenclature has an almost50-year history. As early as 1949 there existed aSubcommission on Nomenclature within the InternationalUnion of Pure and Applied Chemistry (IUPAC) under thechairmanship of Maurice L. Huggins. The Subcommissionwas part of the IUPAC Commission on Macromolecules,chaired then by Herman F. Mark. Other notable pioneers inpolymer science, Jan Joseph Hermans, Otto Kratky, HarryW. Melville, and George J. Smets, were members of theCommission.

The Subcommission produced its first official report in1952. It recognized then, what is just as true today, that thepractice in the field of small molecules of providingrigorous definitions is impractical for polymers. The latterconsist of molecules not necessarily exactly of the samesize, chemical composition, or structure. The differencesresult from the presence of end groups, branches, variationin orientation of monomeric units, and irregularity in thesequence of different types of units.

The American Chemical Society (ACS) Division ofPolymer Chemistry established its Nomenclature Commit-

tee in 1963 to try to unify earlier attempts to name polymersin some coherent way. Their first major project resulted in astructure-based nomenclature for regular linear polymers,first published in ACS Polymer Preprints in 1967, adoptedby Chemical Abstracts in 1968, and incorporated in IUPACrecommendations in 1975 [I].

When the IUPAC Commission on Macromolecules waselevated to become the IUPAC Division of MacromolecularChemistry, the latter in turn established its Commission onMacromolecular Nomenclature in 1968.

The Commission in the course of its nearly 30 years ofexistence produced a series of major documents that haveshaped modern nomenclature and terminology of polymerscience. The recommendations are being published in theIUPAC official journal, Pure and Applied Chemistry, andoccasionally are republished in the form of a "Compen-dium" which groups all the currently valid documents in asingle volume. The Commission published its "Compen-dium of Macromolecular Nomenclature" in 1991 [2]. Thebook, which IUPAC has designated the "Purple Book", inanalogy to other IUPAC books ("Blue" - organic, "Red"- inorganic, "Orange" - analytical, "Green"- physical,and "Gold" - overall chemistry), has the two most basicmacromolecular nomenclature recommendations: "nomen-clature of regular single-strand organic polymers" and"source-based nomenclature for copolymers". In morerecent years, the Commission extended that basic nomen-clature to double-strand (ladder and spiro) organic poly-mers, irregular and crosslinked polymers, and polymerblends and interpenetrating networks.

In this article, the basic structure-based and source-basednomenclature of polymers is explained and illustrated insome detail. The continuing use of common andsemisystematic nomenclature with reference to specifictables in this Handbook is highlighted. The currentChemical Abstracts (CA) index names [3] are comparedand contrasted with the IUPAC practice and typical namesemployed in the polymer journals and textbooks.

B. IUPAC RECOMMENDATIONSSince polymers, unlike low-molecular-weight compounds,have no uniform structure and are mixtures of macro-molecules of different length and different structural

arrangement, their graphical representation and their namesrequire a special approach.

Often enough, the structure of the polymer has not beensufficiently characterized and the researcher cannot draw itschemical structure. Consequently, no name of the polymerreflecting its structure is possible.

A polymerization reaction for a polymer formed froma monomer such as vinyl chloride can schematically berepresented by

That shows an idealized product. In fact, however, thepolymer consists of long-chains of various lengths. Therepeating units, - C H 2 - C H C l - , are not necessarily alluniquely oriented and joined in a regular fashion as shownin the idealized structure above. In addition to "head-to-tail" links

other links such as "head-to-head"

and "tail-to-tail"

can occur, and the exact sequence of all these repeatingunits usually is not known.

This becomes even more complicated when a copolymeris derived from more than one monomer, such as styreneand methyl acrylate, which contribute two constitutional ormonomeric units:

They can combine into a polymeric chain, resulting inmany types such as unspecified, statistical, random,alternating, periodic, block, or graft copolymers.

Because the exact structure of the polymer is not alwaysknown, two systems of naming polymers exist:

source-based nomenclature,structure-based nomenclature.

1. Source-Based Nomenclature1.1. Homopolymers Homopolymers are derived fromonly one species of monomer, which may be the actualstarting reactant (or source), or be a hypothetical monomerif the homopolymer is formed by a modification of anotherhomopolymer.

The name of the polymer is formed by attaching theprefix "poly" to the name of the actual or assumedmonomer, or the starting reactant (source), from which thepolymer is derived.Examples: poly (acrylic acid)

polyacrylonitrile

polybutadienepolyethylenepoly(methyl methacrylate)poly(methyl vinyl ether)polystyrenepoly(tetrafluoroethylene)poly(vinyl alcohol)poly(vinyl acetate)poly(vinyl chloride)poly(vinylidene dichloride)

Parentheses are used when the name of the monomerconsists of two or more words, and when the monomer hassubstituents.

These are all olefinic type reactants, from which twocarbon atoms originally linked by a double bond form abivalent group:

where R and R[ represent a hydrogen atom or a substituentgroup. Many of these are joined, in turn, to each other buttheir exact orientation or sequence is seldom known.

On the other hand, different polymers derived from asingle monomer and having identical constitutional unitscan still be differentiated by additional information, such asaverage molecular weight and other chemical and physicalcharacteristics.

1.2. Copolymers For copolymers, the names of mono-mers are cited after the prefix "poly". In addition, anitalicized connective (infix) is placed between the names ofmonomers to denote the kind of sequential arrangement bywhich the constitutional (monomeric) units, derived fromeach monomer, are related in the structure [4].

Seven types of sequence arrangements are listed withtheir corresponding connectives:

Type Connective

unknown or unspecified -co-statistical (obeying known statistical laws) -stat-random (obeying Bernoullian distribution) -raft-alternating (for two monomeric units) -alt-periodic (ordered sequence of more than two) -per-block (linear arrangement of blocks) -block-graft (side blocks chains connected to -graft-

main chain)

Examples: poly[styrene-C(?-(methyl methacrylate)!poly^tyrene-statf-acrylonitrile-statf-butadiene)poly[ethylene-ran-(vinyl acetate)]poly[(ethylene glycol)-tf/r-(terephthalic acid)]poly[formaldehyde-/?er-(ethylene oxide)-per-

(ethylene oxide)]polystyrene-&/oc&-polybutadienepolybutadiene-gra/f-polystyrene

The names of the monomers are those common orsemisystematic names that are encountered most often inthe literature of polymer science. The order of citation ofmonomers in copolymer names is arbitrary.

An equally acceptable alternative scheme for namingcopolymers utilizes the prefix "copoly", followed bycitation of the names of the monomers, separated by anoblique stroke (a solidus). Parentheses are not needed toenclose monomer names consisting of two or more words.

Examples: copoly(styrene/methyl methacrylate)j"tatf-copoly(styrene/acrylonitrile/butadiene)ran-copoly(ethylene/vinyl acetate)a/f-copoly(ethylene glycol/terephthalic acid)per-copoly(formaldehyde/ethyleneoxide/ethy-

lene oxide)Wtfc/:-copoly(styrene-butadiene)gra/-copoly(butadiene-styrene)

1.3. Nonlinear Macromolecules and MacromolecularAssemblies Most recently, the source-based nomenclaturehas been extended for non-linear macromolecules andmacromolecular assemblies [5], The non-linear macromo-lecules comprise branched, graft, comb, star, cyclic, andnetwork macromolecules. The macromolecular assembliescomprise polymer blends, interpenetrating polymer net-works, and polymer-polymer complexes.

The following italicized qualifiers can be used as bothprefixes (e.g., blend-, net-) and infixes (connectives) (e.g.,-blend-, -net-) to designate the skeletal structure of non-linear macromolecules or macromolecular assemblies:

Type Connective

cyclic cyclobranched, unspecified branchshort-chain-branched sh-branchlong-chain-branched l-branchbranched with branch point

of functionality / f-branchcomb combstar starstar with / arms f-starnetwork netcrosslink t (Greek iota)polymer blend blendinterpenetrating polymer network ipnsemi-interpenetrating polymer network sipnpolymer-polymer complex compl

In naming non-linear homopolymer molecules, theitalicized prefix for the skeletal structure of the macro-molecule is placed before the source-based name of theconstituent linear chain.

Assemblies of macromolecules held together by non-covalent bonds are named by a combination of the names of

the constituent macromolecules with an italicized con-nective between them.

Examples: poly styrene-com>-poly aery lonitrilecom&-poly(styrene~statf-acrylonitrile)poly styrene-comZ?- [poly acrylonitrile;

poly(methyl methacrylate)]4-sfar-polystyrenestar-(po\yA-block-polyB-block-polyC)star-(polyA; polyB; polyC)star-(polyacrylonitrile; polystyrene)
