DEFINITION

Classification: 527/100

FROM REACTANT WHICH IS A CELLULAR MATERIAL DERIVED FROM PLANT OR ANIMAL SOURCE AND IS OTHER THAN DIATOMACEOUS EARTH, BLOOD, COTTON, OR FARINACEOUS FLOUR, E.G., CITRUS PULP, WALNUT SHELL FLOUR, ETC.:

(under subclass 1) Subject matter under Class 520, ... wherein a solid polymer is derived from a reactant which is a plant or animal material which retains at least some of the original cell structure, e.g., citrus pulp, wood, flour, etc., and excluding diatomaceous earth or fossilized matter (e.g., chalk, etc.), blood, cotton, or farinaceous flour or meal and a reactant which an ethylenic monomer, SICP or SPFI; or process of preparing said polymer.

(1) Note. Soybean flour or meal is included herein, also peanut and cottonseed meal.

(2) Note. Included herein are fibrous materials such as bark obtained from woody plants (e.g., mimosa bark, cork, etc.).
