The microstructure and rheological properties of the crosslinked polymer microspheres

The method to analysis the rheological property of the crosslinked polymer microspheres is presented in this paper. The flow curves and hysteresis loop areas of different swelling time and different mass concentrations of microspheres gotten. Through the above experimental data, the flow pattern and the time-dependent property are judged. Combined with the environmental scanning electron microscope images of microspheres, we can draw the conclusion that the concentration has obvious effects on the rheological property of the microspheres.
