Abstract
Using capillary rheometer to study PPS temperature, shear rate, activation energy of viscous flow. Experiments show that with the increase of shear rate, apparent viscosity decreased. As the apparent viscosity is affected by temperature, so when the temperature increased, the apparent viscosity also decreased. It also indicates that the higher the shear rate comes, the lower the impact of temperature on the apparent viscosity is. As the temperature increased, non-Newtonian index (n) increased and tended to 1, PPS melt is pseudoplastic fluid. The activation energy of viscous flow of PPS decreased with the increasing of the shear rate. In addition, with the increasing of temperature, structural viscosity index felt regularly.
