Abstract

Volatile pyrolysates of a methyl methacrylate‐butadiene‐styrene copolymer (MBS) have been analyzed using a capillary gas chromatograph equipped with a Fourier transform infrared detector in tandem with a mass selective detector, and a gas chromatograph‐atomic emission detector system.

Among the volatile compounds observed were monomers used for synthesis of the polymer. Numerous oligomers of higher boiling point were also found; identification of these could be used to give structural information about the parent polymer.

Combining information from these techniques was found to be extremely useful for the analysis of polymer pyrolysis products. In characterizing each compound it was found particularly helpful to juxtapose feature‐specific chromatograms (e.g., single ion monitoring from the mass‐selective detector and the selected wavelength chromatography from the infrared detector).
