VIBRATIONAL AND NMR SPECTROSCOPIC STUDIES OF A THIOLSULFONATE PRODUCED FROM THE NONCATALYTIC HYDROGENATION OF POLYBUTADIENE

Mass spectrometry, H-1 NMR, C-13 NMR, 2D NMR, FT-IR and Raman spectroscopy have been used to establish the structure of a thiolsulphonate by-product in the non-catalytic hydrogenation process for polybutadiene, which makes use of p-toluene sulphonylhydrazide as a reaction intermediate. The formation of this product has not been reported previously under such conditions. Spectroscopic evidence is presented for the molecular structure.
