Class Information
Number: 527/100
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > 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.
Description: 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.
