| Abstract: |
| The dynamic rheological behavior of liquid IR (LIR) was investigated by dynamic rheometer.It was showed by shear rate scanning that the shear rate had little effect on the viscosity of LIR except for the high shear rate；it was showed by temperature scanning that the rheological behavior was very sensitive to the temperature，and LIR was slightly cross-linked at the higher temperature(above 130 ℃) to increase the viscosity remarkably；and the dependence of the LIR's viscosity on the temperature could be described by Arrhenius' equation，and the flow activation energy of LIR calculated from the viscosities at the zero shear rate and different temperatures was 39.27 kJ·mol-1. |
