DEFINITION

Classification: 522/168

Processes of preparing a solid polymer from a heterocyclic chalcogen monomer; or compositions therefore:

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

therefore.

(1) Note. Chalcogen is limited to oxygen, sulfur, selenium or tellurim.

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

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