Abstract
This article describes the preparation of a functional novolac having electron withdrawing groups (nitro groups) by a polymer reaction of a novolac derivative. o-t-Buthylphenol novolac (a precursor) (2) was prepared by the HCl-catalyzed addition-condensation of o-t-buthylphenol with paraformaldehyde in a good yield. Then 2 was regioselectively into o-nitrophenol novolac (3) in good conversion. The structure of 3 was confirmed by IR, lH NMR and GPC analysises, and the property was well-soluble in common organic solvents but insoluble in hexane and water. 3 is expected as an explosive material and a biofunctional polymer.
