Abstract

Acid-catalyzed (novolac type) and base-catalyzed (resol type) condensation products of phenol with formaldehyde were characterized by field desorption mass spectrometry. Novolac resin features spectrum containing molecular ions of polynuclear phenols with methylene linkages between the aromatic nuclei. Resol-type resin produces a wise variety of ionic species of mono- and polynuclear methylolated phenols. Acetylation of resol makes the assignation of condensation products easier. Number average molecular weights obtained by field desorption mass spectrometry agree fairly well with the values calculated from **1H minus NMR spectra.
