DEFINITION

Classification: 524/751

Heterocyclic chalcogen compound as DNRM:

(under subclass 700) Subject matter wherein a heterocyclic chalcogen ring containing material is present as DNRM during formation of a solid polymer or SICP.

(1) Note. By schedule exclusion, the remaining chalcogen atoms proper for this subclass are oxygen, selenium, or tellurium.

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