Abstract
Good reproducibility of the pyrolysis—gas chromatography of vulcanized rubbers is difficult because of their insolubility, the presence of additives and the complexity of the pyrograms. With cis-1,4-polyisoprenes, the quantitative results are considerably improved by using a high-resolution glass capillary column instead of a packed column. The relative standard deviation is about 1% for the main peaks and is still less than 5% for several small peaks.
