Class Information
Number: 525/316
Name: Synthetic resins or natural rubbers -- part of the class 520 series > Synthetic resins (class 520, subclass 1) > Mixing of two or more solid polymers; mixing of solid polymer or sicp with sicp or spfi; mixing of sicp with an ethylenic agent; mixing of solid polymer with a chemical treating or ethylenic agent; or processes of forming or reacting; or the resultant product of any of the above operations > At least one solid polymer derived from ethylenic reactants only > Polymer derived from ethylenic reactants only mixed with ethylenic reactant > Ethylenic reactant contains at least two unsaturated groups and is devoid of an aromatic group > Ethylenic reactant reacted in the presence of a solid polymer substrate derived from reactant containing two unsaturated groups and is devoid of an aromatic group > Ethylenic reactant is an aromatic hydrocarbon
Description: Subject matter wherein the ethylenic reactants reacted with the solid polymer is an aromatic reactant, e.g., poly(butadiene-styrene) reacted with styrene, etc.
