The knowledge on the influence of elastomer-filler interactions on the dynamic properties of elastomeric composites is insufficient, but required for tailoring rubber compounds in terms of mechanical and dynamic properties. The properties of this composite material can be adjusted over a relatively broad range by modification of the polymer-filler interaction. Silica as wildly used filler possesses a high concentration of silanol-groups on its surface, which allows controlling the chemistry of the polymer-filler interaction and the interparticle forces. The silanol groups can react with alkoxy groups of the silane coupling agents, which are commonly used for achieving better dispersion and polymer-filler interaction with silica fillers. Selective changes in the structure of the coupling agent, e.g. the number of alkoxy groups reactive towards silanol groups, the length of the linker between filler and polymer, or the bond strength between coupling agent and polymer, lead to changes in the microstructure of the silica-polymer interface and determine the dynamic properties of the material, thus wet grip and rolling resistance when used in a tire tread. In this study, three different silanes were synthesized: a silane inert towards the elastomer, a silane having only one instead of three ethoxy-groups and a silane with a decyl linker. These silanes were compared to bis-(triethoxysilyl)propyltetrasulfide (TESPT), the commonly used coupling agent for silica, in a concentration study on equimolar basis. It was shown that these changes in the silane structure lead to characteristic changes in the bulk properties of the composites. The application of silanes inert towards the elastomer results in a decrease in tensile properties. A longer linker lowers the hysteresis at elevated temperatures, thus a lower energy loss at the service temperature of a running tire. And silanes with just one ethoxy group decrease the hysteresis at high temperatures and increase it at low temperatures. In this paper, the effect of specific changes in the structure of the silane coupling agent on the dynamic and mechanical properties as indicators for tire performance will be discussed.
