DEFINITION

Classification: 524/800

Preparation of intentional or desired composition by formation of solid polymer or SICP in the presence of water as a designated nonreactant material (DNRM), or products thereof:

(under subclass 1) Subject matter under Class 523, ... wherein a desired or intentional composition is produced by formation of a solid polymer or SICP in the presence of water as a designated nonreactant material or products thereof.

(1) Note. Included herein are chemically aftertreated products and the process of chemically aftertreating where no NRM is added subsequent to the initial in situ solid polymer formation.
