FT Raman spectroscopic study of the diimide hydrogenation of cis-polybutadiene: Some evidence of cis—trans isomerization

Abstract

The diimide hydrogenation of cis-polybutadiene is studied. p-Toluenesulfonylhydrazide is used to fully and partially hydrogenate cis-polybutadiene. The microstructure and hydrogenation of the samples obtained are subsequently studied by FT Raman spectroscopy. Cis—trans isomerization is found to take place during the reaction. A mechanism of isomerization and hydrogenation is also proposed.
