| 摘 要： | The rheological behavior of polyhexamethylene guanidine hydrochloride (PHGC) and polyhexamethylene guanidine stearate (PHGS) has been investigated using the capillary rheometer. It is shown that the polyelectrolyte melts are non-Newtonian of shear-thinning fluid. The melt viscosity, die flow activation energy and the flow temperature are high even if the molecular weight is not high. The melting viscosity of PHGC is higher than that of PHGS at the same experimental conditions. By comparison with the case of PHGS the non-Newtonian index of PHGC is smaller, the flow activation energy and die flow temperature of PHGC are higher, which was caused by the difference in their molecular structure.
