Modified Polymers
The terms in the modified polymers facet can be used either on their own or in combination
with polymer formers, polymer types or chemical aspects.
We have also expanded the coverage to include indexing of specific modifying agents for
polymers. For this, we index the SCNs, generic codes and/or chemical aspects of compounds
which have been exemplified or claimed as such.
Chemical Aspects
In this section we cover the Chemical Aspects in detail, including the rules and definitions used
in applying them. For Graphical definitions of the Specific functionality terms, see the Polymer
Indexing Reference Manual.
Within the Chemical Aspects facet there are both general terms and specific terms. The
general terms (of format Dnn) are applied in the widest reasonable sense; for example, Acid
halide (D64) - any acid as conventionally understood is included, and thus the term embraces
sulphonyl halides, phosphonyl chlorides etc. The terms acid, base, salt etc. are used in their
conventional sense.
General terms
Inorganic compounds are represented by the concept Inorganic (D00) plus the element terms
and appropriate specific functionality terms. D61 Salt/complex is not applied to inorganic
salts.
Organic compounds are represented by any of the concepts which are applicable, but the
element terms for Carbon (C-) and Hydrogen (H-) are not applied to organic compounds.
