Synthesis and Electrical Conductivity Studies of Metal Chloro and Nitroxide Group Containing Styrene Butadiene Rubber

The introduction of different functional group in SBR was done by a simple reaction between sodium nitrite and mercuric chloride in the presence of phase transfer catalyst. The attachment of chlorine and NO2 functional group in the double bond of the butadiene was monitored by FTIR and UV spectroscopy. The structure and morphology of chloro nitro SBR was studied by SEM and XRD. Flame retardency studies revealed that the chemical modification imparts better flame resistance to chemically modified SBR. AC conductivity and dielectric properties of chloro-nitro SBR was higher than that of SBR and conductivity increases with the level of chemical modification.
