DEFINITION

Classification: 526/59

(under subclass 1) Subject matter under Class 520, ... wherein a process parameter is determined and some polymerization process parameter is altered in response to the determination.

(1) Note. A test or measurement performed by a human being with a subsequent control operation is proper herein.

(2) Note. Treating a material to a certain condition without a defined inanimate measurement, test, inspection, or control (e.g., temperature, pH, etc.) is not proper subject matter for this subclass and classification of such a process will be accorded on some other basis.
