Abstract:
      The effect of silica content and types of silane coupling agents on extrusion and rheological properties of ESBR was investigated, and the grafting efficiency of the three kinds of silane 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 increase of silica content at high shear rate. The viscosity and Payne effect of silica-Si747 filled system were the highest, and the appearance of extrudate was roughness, when the silica content was 40phr. However, the extrusion-temperature stability was better. The modification effect of Si69 and Si75 on silica was not different obviously.
