摘要：
The capillary how properties of novel engineering thermoplastic phenolphthalein poly(ether ether ketone) (PEK-C) have been investigated using capillary rheometer. The dependence of viscosity on the wall shear rate and temperature were obtained. The entrance effect was calculated and from which the extensional behavior was also estimated. From the extudate swell ratio the principal normal stress were also evaluated. The melt fracture phenomena were checked and discussed.
