| Abstract: | The relationships between the vinyl content and the properties as well as the network density of solution polymerized SBR (S-SBR) were studied. The results showed that with increasing the vinyl content, the Tg, optimum cure time , wet skid resistance and rolling resistance of S-SBR increased, the hardness, rebound, 300% tensile modules, heat build up and tear strength decreased. The rolling resistance was improvedwith increasing molecular weight. When the vinyl content increased from 16% to 57% , the density of entanglement, chemical crosslink and carbon black networks decreased about 24%, 25% and 5% respectively. |
