Class Information
Number: 525/123
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 > With saturated -n=c=x (x is chalcogen) reactant or polymer thereof; or with solid copolymer derived from at least one -n=c=x reactant wherein at least one of the reactants forming the solid copolymer is saturated; or with spfi wherein at least one of the necessary ingredients contains a -n=c=x group or with a reaction product thereof; or with sicp containing a -n=c=x group
Description: Subject matter wherein, in addition to the solid polymer derived from ethylenic reactants only, there is additionally present (a) a saturated -N=C=X (X is chalcogen) reactant or a polymer thereof, or (b) a solid copolymer derived from a -N=C=X -containing reactant wherein at least one of the reactants forming the solid copolymer is saturated, or (c) specified polymer-forming ingredients wherein at least one of the necessary ingredients contains a -N=C=X group and at least one of the necessary polymer-forming ingredients is saturated or a reaction product or condensate thereof, or (d) a specified intermediate condensation product which contains a -N=C=X group.
