DEFINITION

Classification: 522/167

Processes of preparing a solid polymer from heterocyclic nitrogen monomer; or compositions therefore, e.g., carbazole, etc.:

(under subclass 1) Subject matter wherein a monomer containing a nitrogen atom as part of a heterocyclic ring is polymerized so as to form a solid polymer; or compositions therefore.

(1) Note. See Class 520, Glossary, for a definition of the term "heterocyclic".

(2) Note. See General Summary of Subject Matter Within This Class in the class definition for the type of composition proper for this subclass.
