Claim 7:
8. An article of manufacture, comprising:
a material containing a flame retardant levulinic acid-based polymer,
wherein the flame retardant levulinic acid-based polymer is a polymer that includes a flame retardant levulinic acid-based compound, and wherein the flame retardant levulinic acid-based compound has a formula of:, wherein M1 is a moiety selected from a group consisting of a phenyl-substituted flame retardant group and an R-functionalized flame retardant group;
wherein M2 is a methylene bridge group;
wherein M3 is a moiety selected from a group consisting of the carbonyl group, a methine group with an ether-linked phenyl-substituted flame retardant group, and a methine group with an ether-linked R-functionalized flame retardant group; and
wherein M4 is a moiety selected from a group consisting of a methyl group, a methylene bridge to an ether-linked phenyl-substituted flame retardant group, a methylene bridge to an ether-linked R-functionalized flame retardant group, a phenyl-substituent, a thioether-linked phenyl-substituted flame retardant group, and a thioether-linked R-substituted flame retardant group.
