NOMENCLATURE AND GRAPHIC REPRESENTATIONS FOR CHEMICALLY MODIFIED POLYMERS (IUPAC Recommendations 2014)
2015
Abstract
A new source-based nomenclature system is described which indicates that a particular polymer has been chemically modified. A connective within the name of a polymer, -mod-, is introduced for this purpose as in poly[(A)-mod-(B)].
The system is intended to be used in accordance with source-based naming of polymers but also provides for the use of structure-based names when it is unavoidable. It embraces: (1) modification of a constitutional unit into another, the unique structure of which is known; and (2) a more general modification of a constitutional unit resulting in any one of a number of possible structures.
In addition, a new symbol, ~>, is proposed for use in graphic representations of the structure of modified polymers.
