The presence of the thiol group in TRM was studied via FT-IR spectroscopy. Pure sample of Plain gum mixture (PM) and thiolated reaction mixture (TRM)were scanned by Fourier Transform Infra-Red spectrophotometer (Shimadzu Affinity-1). KBr pellets of samples were prepared by applying pressure of 10 ton and FTIR spectra was recorded in a range of 4500–500 cm−1 [27 (link),28 (link)].
