Abstract: Present study deals with an attempt to modify the surface chemistry of N330 carbon black by the interaction with aromatic derivatives. Two aromatic polyhydroxy compounds, namely 1,2 dihydroxy benzene (catechol) and 1,2,3 trihydroxy benzene (pyrogallol) are chosen as surface modifiers. It has been shown that the lone pair of electrons of the oxygen has contributed to the higher interaction with existing functional groups of carbon black giving an increased crosslinking density. The surface modified carbon black when compounded with natural rubber has produced rubber compounds with improved rheological and visco-elastic properties. It has been noted that dynamic mechanical properties like heat build-up and hysteresis loss have also been improved and in some cases improved abrasion loss properties have been achieved. The results indicate that there has been as enhancement of filler-polymer interaction with a reduction of filler-filler networking. The effect of increased crosslinking phenomenon and filler-polymer interaction are more pronounced for catechol than that for pyrogallol.
