Class Information
Number: 525/314
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 > Block copolymer derived from reactant containing at least two unsaturated groups and is free of an aromatic group
Description: Subject matter wherein the polymer is a block copolymer derived from an ethylenic reactant containing at least two ethylenic groups which ethylenic reactant is free of an aromatic group, e.g., block copolymer of (polybutadiene-polypropylene).
