Direct Analysis of Tackifying Resins in Vulcanized Rubber by Simultaneous Pyrolysis Methylation-Gas Chromatography/Mass Spectrometry
Seung Wook Kim*, Gwi Suk Heo, Gae Ho Lee
Vulcanized rubber containing three kinds of oligomeric resins such as cashew resin, t-octylphenol formaldehyde resin and terpene modified wood rosin has been characterized by simultaneous pyrolysis methylation-gas chromatography/mass spectrometry (SPM-GC/MS). After methylation by the SPM method using tetramethylammonium hydroxide, the methylated pyrolyzates of the corresponding resins were detected with higher sensitivity than underivatized pyrolyzates without any interferences from other ingredients of vulcanized rubber.
