| Abstract: |
| The effects of silica content and silane coupling agents on the rheological properties of filled ESBR during extrusion were investigated，and the grafting efficiency of the 3 kinds of silane coupling agents was analyzed. The results showed that the non-Newton index of silica filled system was independent on its content at low shear rate. However，the non-Newton index of this system increased with the increasing of silica content at high shear rate. When the silica content was 40 phr，the viscosity and Payne effect of silica/Si747 compound was the highest，and the appearance of extrudate was rough. However，the extrusion temperature stability was better. The modification effects of Si69 and Si75 on silica were not significantly different. |
