| Abstract: |
| The microstructure，rheological properties and die swell of clay/SBR nano-composite and carbon black/SBR compound were investigated with TEM and Monsanto rheometer.The results showed that both clay and CB were dispersed in SBR on nanoscale，but the clay particles were in sheet
form and CB particles were in spheric form，and the rheological properties of two compounds were quite different；the viscosity of clay/SBR compound was higher than that of CB/SBR compound at the same loading level；and the clay/SBR compound could be extruded at the higher speed because it had better extrudate appearance and smaller die swell when compared to CB/SBR compound. |
