摘要：

Wall slip of styrene-isoprene-styrene (SIS) triblock copolymer was investigated during the capillary extrusion flow. The origin of the unique flow behavior of SIS was explored. Wall slip velocity of the SIS at 150 degrees C was calculated by the Mooney method. The non-monotonic wall slip behavior exhibited by the SIS system in the weak wall slip region was due to the change of PS micro elastic phase. SAXS and DMA data confirmed that SIS had a viscous flow transition near 170 degrees C. The occurrence of this transition caused a significant change in the flow curve and wall slip state of the SIS.
