Many countries introduced emission standards and labeling systems focused on tires. Particularly, the rolling resistance of the tire is one of the most important factors for fuel efficiency and the emission of greenhouse gases in vehicle. For solving those issues, it is necessary to use silica filler in the manufacture of green tires which show good wet traction and low rolling resistance compared to carbon black. However, silica shows low compatibility with non-polar diene polymers due to the hydrophilic silanol groups that exist on the silica surface. In the present study, GMA-SBRs with different wt% of GMA content in a range of 0.06–0.71 wt% was polymerized as rubber to improve compatibility between rubber and silica for silica-filled tire tread compound. The effects of the GMA content and number of epoxy group in a molecular chain are investigated and we determined the best content of GMA in GMA-SBR for high performance silica-filled tire tread compound while maintaining dynamic viscoelastic properties. Styrene-butadiene-glycidyl methacrylate terpolymers (GMA-SBRs) were synthesized by cold emulsion polymerization with different wt% of GMA content for the fuel efficient tire composite. After compounding with silica filler, cure characteristics, mechanical and dynamic properties of the various GMA-SBR/silica composites were analyzed. Mechanical properties of the composites were increased as GMA content increases. However, the optimum content of GMA in the GMA-SBR was ~0.6 wt% in terms of dynamic properties such as Payne effect and tan δ at 60°C, representing rolling resistance of the tire. These results are due to the improvement of silica dispersion in the composites. The present approach assists in determination of the functional group content in the functionalized emulsion styrene-butadiene rubber (F-ESBR) for fuel efficiency and decrease of greenhouse gases from vehicles.
