DEFINITION

Classification: 522/71

Processes of preparing or treating a solid polymer by wave energy in the presence of a designated nonreactant material (DNRM); or composition therefore:

(under subclass 1) Subject matter involving the preparation or treatment of a solid polymer in the presence of wave energy and in the presence of a designated nonreactant material (DNRM); or a composition to be polymerized to produce a solid polymer in the presence of a DNRM; or a composition containing a solid polymer to be modified in the

presence of a designated nonreactant material (DNRM).

(1) Note. See the Glossary in this class (522) for a definition and examples of the term "designated nonreactant material" (DNRM).

(2) Note. For proper classification in this subclass, the designated nonreactant material must be present during the wave energy treatment and must exercise a function subsequent to the wave energy step. A material which functions prior to the wave energy step and which function is destroyed or not intended subsequent to the wave energy step is not proper for this subclass.

(3) Note. By schedule exclusion the subject matter in this area may have a nonspecified rate-affecting material included.

(4) Note. In the subclasses below which recite a designated nonreactant material (DNRM) in the title, the indented subclasses merely pertain to a further elaboration of the DNRM and do not relate to any other material.

(5) Note. This subclass provides for compositions perfected as to be utilized in a process involving wave energy and a DNRM material.
