Summary

Inverse gas chromatography with sulphurated olefinic stationary phases and air as carrier gas has been found to yield characteristic shifts of retention data. The resulting plots of retention index versus reaction time obtained for a range of squalene vulcanizates have been found to be similar to those given by oxygen absorption measurements. Furthermore the chromatographic oxidation curves have been found to be consistent with the known oxidation behaviour of the various sulphur networks formed on vulcanization.
