The general purpose of this study is to investigate the effect of lubricant inclusion on the rheological behaviour and residence time of polymeric materials during single screw extrusion. The residence time distribution was consequently calculated by means of ``styrofoam-particulate tracer method'' developed for our experiments including the single screw extrusion of ethylene vinyl acetate copolymer coated with stearic acid used as the lubricant. Tests were performed and data were reported for three different screw speeds performed at 70° operating temperature value.
