Fast Atom Bombardment Mass Spectrometric Characterization of Poly(O-Toluidine)

Abstract

Fast atom bombardment (FAB) mass spectrometry has been used to analyze chemically prepared and fractionated poly(O-toluidine) of low molecular weight (m/z < 5800) to evaluate its potential for the characterization of polymers of similar structure. In the lower mass range (m/z 400-1800) ionic species detected are separated by the mass of a toluidine monomer unit (m/z = 105). An interesting feature of the mass spectra is the observation that the apparent main component of poly(o-toluidine) contains one oxygen atom per chain. This is further confirmed by MS/MS analysis of selected ions. Several possible reasons for the presence of oxygen in the polymer are discussed. All results support the proposed structure of the polymer and demonstrate that FAB-MS can provide detailed structural information on the electrically conductive poly(o- toluidine) and related compounds.
