Title: Definitions of terms relating
to individual macromolecules, their assemblies, and dilute polymer
Remark: this project is a revision
of the 1988 IUPAC Recommendations published as Pure Appl. Chem.
61, 211-241 (1989) and also as Chapter 3 of the 1991 "Compendium
of Macromolecular Nomenclature" (the Purple Book) >

To revise and amend the new terminologies on the IUPAC Recommendation:
Definitions of Terms Relating to Individual Macromolecules, Their
Assemblies, and Dilute Polymer Solutions (Pure Appl. Chem.
61, 211-241 (1989)). The document, published in 1989, deals
with terminology in key areas of the physical chemistry of macromolecules
as individual macromolecules, their assemblies and dilute polymer
solutions; it includes recommended terminology for molecular weight,
molecular-weight averages, distribution functions, radius of gyration,
the Flory-Huggins theory, viscosity of solutions, scattering of
radiation by polymers, fractionation, etc. Since late 70's, there
has been a rapid progress in understanding the physical properties
of macromolecules in concentrated solution and in bulk, which was
not matured enough when the document was prepared. Also, it is (required)
desirable to take action against some frequently used improper terms.
Therefore, it is (necessary) urgent to revise and expand the terminology
on the physical properties of macromolecules in solution and publish
it as a superseding recommendation, which will also be incorporated
in one of the next new editions of the Purple Book.
The document deals with the terminology of macromolecules in solution,
individual macromolecules and macromolecular (aggregations) assemblies.
Chemical terminology, is (typical and unique field of activity)
one of the basic terms of reference of IUPAC. Its update is also
of great importance for the recently started project on terminology
in separation techniques. The document will include newly introduced
terms in the field of physical properties of macromolecules in various
states, particularly in concentrated solutions and in bulk.
