Abstract

The vane plasticating extruder (VPE) is a novel polymer processing equipment which is based upon elongational rheology. According to the basic structural analysis and movement interpretation, generation mechanism of elongational flow field was derived. Elongational effects during the controlled recovery of immiscible polymer blends, containing polystyrene (PS) matrix and linear low density polyethylene (LLDPE) as dispersed phase, were studied. The morphological results revealed the elongational effect of vane extruder. LLDPE morphology evolution was precisely predicted by a mathematical model. Elongational ratio and elongational strain via VPE were calculated separately, both of which established that the VPE does imposed elongational force field on polymer blends.
