## Abstract Data presented for a range of vulcanized rubbers prepared under different conditions show that while olefinic unsaturation becomes reduced by vulcanization in the proportion of one double bond for each sulphur atom combined with a C~5~Hβunit, the original H/C ratio of 8/5 is not altered
