Abstract:
A pyrolysis-gas chromatographic method for the routine identification of elastomeric materials is described. Elastomers previously identified by pyrolysis-infrared spectrophotometry were pyrolyzed in the injection port of a gas chromatograph. The pyrolysis products were separated on one column using a single set of chromatographic conditions. Reproducible pyrograms were obtained. A pyrogram catalog of commercially important elastomers was compiled to be used as a reference for identifying these materials. As a further aid in identification, the retention times of the major pyrolysis product-peaks were recorded with the aid of a digital integrator. Author
