DEFINITION

Classification: 526/272

(under subclass 271) Subject matter wherein the 5-membered oxygen-containing ring is interpolymerized with at least one unsaturated monomer which is solely composed of hydrogen and carbon atoms.

(1) Note. This subclass includes interpolymers and other interpolymers wherein other unsaturated monomers, in addition to a hydrocarbon monomer, are polymerized with the unsaturated heterocyclic oxygen-containing compound.
