46 69 * * * Analysis of Vulcanised Rubbers Kenji TAKEMOTO*, Hiroyuki WATANABE* and Fumio NAKAMURA* *Central Customs Laboratory, Ministry of Finance 6-3-5, Kashiwanoha, Kashiwa, Chiba 277-0882 Japan We made various vulcanised rubbers and examined the method to detect the structure of vulcanisation with sulphur. By using solid state 13C nuclear magnetic resonance spectrometry (13C-NMR) and pyrolysis gas chromatography (Py-GC), we detected the structure of vulcanisation with sulphur in natural rubber (NR). And by using raman spectrometry and Py-GC, we detected the structure of vulcanisation with sulphur in styrene-butadiene rubber (SBR).
