What is claimed is: 1. A method of preparing a phenolic polymer, comprising: a) protecting at least one hydroxyl group of a substituted or unsubstituted phenol represented by Structural Formula (XXIX): wherein: R11, R12, R13, R14 and R15 are independently--H,--OH,--NH,--SH, a substituted or unsubstituted alkyl or aryl group, a substituted or unsubstituted alkoxycarbonyl or aryloxycarbonyl group, a substituted or unsubstituted alkoxy group or a saturated or unsaturated carboxylic acid group; or R11, R12, R13, R14 or R15 in conjunction with an adjacent R11, R12, R13, R14 or R15, forms a substituted or unsubstituted alkylenedioxy group; provided that at least one of R11, R12, R13, R14 and R15 is a tert-butyl group 1-ethenyl-2-carboxylic acid or ester thereof, a substituted or unsubstituted alkylene dioxy group or a substituted or unsubstituted n-alkoxycarbonyl group, at least one of R11, R12, R13, R14 and R15 is a hydroxyl group, and at least one of R11, R12, R13, R14 and R15 is--H; with a protecting group, wherein-thereby obtaining one or more protected hydroxyl groups; and b) polymerizing the substituted or unsubstituted phenol, thereby obtaining the phenolic polymer. 2. The method of claim 1, wherein the substituted or unsubstituted phenol is an antioxidant. 3. The method of claim 1, wherein the one or more protected hydroxyl groups are independently at least one of a functional group selected from the group consisting of an ether, ester, silyl ether, carbonate, phosphinate, carbamate, sulfonate, nitrate, phosphoramidate, borate ester, phosphinothioyl ester and sulfenate. 4. The method of claim 3, wherein the functional group is an ether or an ester. 5. The method of claim 4, wherein the functional group is an ester. 6. The method of claim 5, wherein the protecting group is an acetyl group. 7. The method of claim 1, wherein the substituted or unsubstituted phenol is polymerized using an enzyme or an enzyme mimetic. 8. The method of claim 7, wherein the enzyme or enzyme mimetic polymerizes the substituted or unsubstituted phenol in the presence of hydrogen peroxide. 9. The method of claim 7, wherein the enzyme or enzyme mimetic is peroxidase, laccase, tyrosinase, lipase, hematin, a tyrosinase-model complex or a metal-salen complex. 10. The method of claim 9, wherein the enzyme is peroxidase. 11. The method of claim 1, wherein the substituted or unsubstituted phenol is polymerized using a chemical reagent or light. 12. The method of claim 1, further including the step of removing the protecting groups after polymerizing the substituted or unsubstituted phenol. 13. The method of claim 1, wherein the phenolic polymer is an antioxidant. 14. The method of claim 1, wherein the phenolic polymer is electrically conductive. 15. The method of claim 1, wherein one or more of R12, R14 and R15 is a tert-butyl group. 16. The method of claim 15, wherein R11 is--H. 17.
