Analysis of Tackifier Resin by Field Desorption Mass Spectrometry

Abstract

Rosin–glycerol ester, terpene resin, terpene phenolic resin, coumarone resin and petroleum resin, which are major commercial tackifiers, were analyzed by field desorption–mass spectrometry (FD–MS) in the region of m/z 150 ∼ 1600. Each resin showed a characteristic mass spectrum that was related to the monomer composition, and the grades of some resins were differentiated by comparing the mass spectra. Packaging adhesive tapes were treated with organic solvent, and some tackifiers, except for aromatic petroleum resin and coumarone resin, which were mixed with aliphatic petroleum resin, were identified simultaneously in the extracts. It has been shown that FD–MS is an effective and easy method to identify tackifiers and those in adhesives.
