Zusammenfassung:	A static devolatilisation apparatus 1 adapted for devolatilising a viscous liquid 2 comprising a volatile component is disclosed. The apparatus 1 comprises a phase separation chamber 100 in an upper region 5 for treating the viscous liquid 2 in a first devolatilisation step to form a first devolatilised viscous liquid 21, and a distributor sub-unit 200 is located below the phase separation chamber 100 and above a lower sump region 4. The sub-unit 200 has a second discharge region 222 embodied such that it is contacted by the first devolatilised viscous liquid 21, and the region 222 has a surface 223 embodied such that the first devolatilised viscous liquid 21 is treated in a second devolatilisation step. The present invention further relates to a process to devolatilising a viscous liquid using the apparatus 1 and also to the use of the apparatus 1 in the devolatilisation of polymer melt or solution.
