| 中文摘要 | a novel engineering thermoplastic, phenolphthalein poly (ether-ether-sulfone) (pes-c) was blended with a commercial thermotropic liquid crystalline polymer(tlcp), vectra a950, up to 30 weight percent of tlcp. a rheometrics dynamic spectrometer (rds-i) and a ceast capillary rheometer, a rheoscope 1000 were employed to investigate the melt rheology and extrusion behaviour at both the low and high shearing rates. the morphologies of the blends under different shearing were observed with a scanning electron microscope(sem) and correlated to the observed rheology. the principal normal stress differences measured with cone-and-plate geometry give a temperature-independent correlation for both blend and pes-c when they are plotted against shear stress. but the extrudate swell of the blends showed a strong temperature dependence at each shear stress. the concentration dependence of extrudate swell shows a contrary behaviour to that of the inorganic filled system. a reasonable hypothesis based on the relaxation and disorientation of tlcp during flowing in the capillary and exiting was given to explain it. the melt fracture was checked after extrusion from capillary and was discussed. |
