Systematic source-based nomenclature for modified polymers is needed
to facilitate communication between scientists; the existing structure-based
nomenclature is cumbersome and inadequate for describing some polymer
Besides many polymers produced by direct transformation of monomer(s)
through a polymerization process, commercial products containing modified
polymers, which are produced by chemical modification of their precursor
polymers, have been available for well over 75 years, and they continue
to be commercially important. A process-based nomenclature system is
described for modified polymers, which intentionally indicates that
a particular polymer to be named has been chemically modified.
A connective within a name of a polymer, -mod-, is introduced
for this nomenclature as poly(A-mod-B). The nomenclature embraces
- in situ modification of one constitutional unit to another;
- modification by addition of functional groups at partly or completely
unknown sites, and
- modification of a polymer in such a way that specific structural
details of the change are unknown.
May 2006 - The introduction of new nomenclature and terminology
as indicated above requires further careful consideration and extended
discussion beyond that which was envisaged when the project started.
An extension has been approved to facilitate completion of this project
and under the new charimanship of T. Kitayama.
