Commercial aromatic petroleum resins and coumarone resins, the representative tackifiers that constitute pressure-sensitive adhesives (PSAs), were analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS). The optimum analytical method uses dithranol as a matrix with silver trifluoroacetate as a cationizing agent. The aromatic petroleum resins are prepared from C8-C10 fraction produced by petroleum cracking, and the coumarone resins are prepared from indene-coumarone fraction of coal tar. The representative monomer of the C8-C10 fraction is vinyltoluene and those of the indene-coumarone fraction is coumarone. The other major reactive monomers are common in both the fractions, which have similar molecular weights. These resins, however, showed characteristic mass spectra and were discriminated clearly based on their mass spectra. The ion distributions of their pentamers calculated under given monomer compositions also are nearly identical with those of the observed mass spectra. Acetone extracts of PSAs were analyzed by MALDI-TOF-MS, and an aromatic petroleum resin and a coumarone resin were identified successfully.
