| Abstract: |
| A novel Gemini ionic liquid，bis（1-methylimidazolium） mercaptosuccinate（BMimMS），was synthesized by neutralization of N-methyl imidazole and mercaptosuccinic acid，and the structure of BMimMS was characterized.BMimMS was used as the interfacial modifier for silica/SBR composites，and the filler network，curing behavior，physical properties and morphology of the composite were investigated.The results showed that，the cation and anion of BMimMS formed hydrogen bond with siloxane and silanol of silica，respectively.The crosslink density of silica/SBR composites was increased as the addition level of BMimMS increased，but the dispersion of silica was not obviously improved.BMimMS could effectively strengthen the silica-SBR interfacial interaction，and the physical properties and loss factor in low temperature region（-20～0 ℃） were improved by BMimMS，resulting in improved wet skid resistance. |
