The effect of functionalization of random styrene-butadiene copolymers (SBR) and type of functional group on the interaction with fillers like carbon black and silica was analysed. The SBR were functionalized using tin (R3SnCl) and organosilane (RSi(OR')3) compounds. The polymers, functionalized and non-functionalized, were characterized by spectroscopy (FTIR), chromatography (GPC) and differential calorimetry (DSC). Carbon black and silica were used to obtain typical tread specimens, which were characterized in terms of rheometric, mechanical and dynamic-mechanical behavior. The rheometric results indicate that higher modulus (ML and MH) and longer curing times (Tc90) were obtained when silica was used. The 100 and 300% modulus were higher when carbon black was used and the reinforcing index was improved with the presence of functional groups. The tan delta values of functionalized polymers at 50-80°C were lower than those of non-functionalized polymers, indicating that lower rolling resistance is obtained using functionalized polymers. |
