N2 - The modified silica at different temperature (MSaDT) with bis(3-triethoxysilylpropyl)tetrasulfide (TESPT), and MSaDT filled solution styrene butadiene rubber (SSBR) composites were prepared to investigate the effect of temperature on surface modification of silica. The results showed that TESPT was successfully bonded on the surface of silica by chemical bonds. The grafting degree (K) of MSaDT of 50 °C was 62.2% and higher than that at the other temperatures. The thermal weight loss and the size distribution of MSaDT showed that the silanol of TESPT hydrolysates reacted with the surface hydroxyl groups of silica, decreasing the average size and agglomeration of modified silica. For 50°C modified silica/SSBR composite, the static mechanical properties and rubber-filler interaction of the composite were better than those of the others. As far as dynamic mechanical properties are concerned, the 50°C modified silica/SSBR composite owned a best combination of low rolling resistance and high wet skid resistance.
