WebFor recording IR spectra, the rubber materials were cut into small pieces. They were taken in a boiling tube and heated so as to bring them to semi liquid State. From the FTIR spectrum of nitrile rubber, the band arises at 1222 cm-1 attributes to C-N stretching of nitrile content.

WebSpectra were recorded of proprionitrile, benzonitrile, and acrylonitrile adsorbed on chromia–silica. The increased frequencies and integrated areas of the nitrile stretching bands, show that nitriles are linked partly to surface silanols through hydrogen bonding and partly to Chromia ‘acidic’ sites through a σ dative bond. The interaction between … WebCompare PE, PP and polyisobutylene IR spectra below. You should be able to distinguish these three spectra. ... It is also intermediate in the strength of the IR absorption, see nylon Raman and IR patterns above.
