Abstract: The solid polymer deformation was observed on-line by using an assembled vane extruder,and then the effects of material properties,pellet size and process parameters on the deformation were investigated.The results show that (1) polymer pellets are deformed under the compaction of VPCU;(2) the solid polymer of a higher modulus experiences a larger plastic deformation;(3) big polymer pellets are turned into small slices after extrusion by VPCU is done,while small pellets experience a big deformation and then form bonded structure;and (4) the solid polymer deformation decreases with the rise of temperature as well as with the decrease of rotor speeds.

Key words: vane extruder, polymers, deformation, visualization
