Synthesis of a m / p ‐cresol–based novolac resin and its subsequent esterification using di‐ tert ‐butyl dicarbonate ( t ‐BOC) is described. The product has been characterized using techniques of FTIR spectroscopy, one dimensional 1 H NMR, 13 C NMR, and DEPT‐135 spectra. Two dimensional NMR experiments like, COSY, HSQC, and HMBC have been used for exhaustive probing of the microstructural details of the derivatized copolymer. © 2009 Wiley Periodicals, Inc.
