Zusammenfassung:	PURPOSE:To especially accelerate the removal of the volatile component of a resin in an extruder. CONSTITUTION:In the removal of the volatile component of a resin in an extruder, inert gas 11 is blown against the resin flowing the screws 4, 5 in a cylinder 1 and the boundary film on the side of the gaseous phase at the resin phase/gaseous phase interface of the resin is made thin and the partial pressure of the unnecessary volatile component removed from the resin is lowered to perform the removal of the volatile component from the resin.
