The microstructures of hydrogenated polybutadienes produced using different hydrogenation routes, namely the low-temperature hydrogenation using tris(triphenylphosphine)rhodium0) chloride or platinum black catalysts, have been studied by Raman spectroscopy. The same spectroscopic method has also been used to examine the products formed by a hydrobromination reaction. The selectivity of these methods towards the various microstructural units has been quantitatively examined from observation of the v(C~---C) stretching vibrations of the cis-l,4, trans-l,4 and vinyl-l,2 components in the polymer. The isolation and spectroscopic characterization of an intermediate formed during the hydrogenation of polybutadienes using tris(triphenylphosphine)rhodium0) chloride is also reported.
