摘要

<正> Blends of polyphenylene sulfide （PPS） containing trace amounts of branching and/orcross-linking in chain and Polyamide-66（PA-66） have been prepared by melt blending. Therheological behavior of PPS/PA-66 blends has been studied by means of capillary rheo-meter

and compared with PPS. The effects of shear rate

shear stress and temperature onthe flow of PPS/PA-66 blends and PPS are discussed. The non-Newtonian indexes andthe activation energies of viscous flow are obtained. The results show that the apparentviscosity of PPS/PA-66 blends is not sensitive to shear rate and stress

but decreases withthe elevation of temperature. On the contrary

the apparent viscosity of the PPS decreasesobviously with the increasing of shear rate and shear stress

but it is increased by theelevation of temperatue.
