摘要：

A mass spectrometric investigation has been performed on the gases evolved during the pyrolysis of natural and some synthetic rubbers over the temperature range 30-450-degrees It was found that variations in ion ratio with temperature reveal interesting structural information. The ion ratio-temperature profiles of the ions representative of styrene and butadiene in block copolymers are very similar to the corresponding ratios for the homopolymers but differ appreciably from those for the statistical copolymers. These ion ratio-temperature plots display stronger structural features if the polymer main chain contains pendant groups.
