Zusammenfassung:	Apparatus and process for the steam isolation of elastomeric alpha -olefin polymers from organic solvent solution by atomizing the solution with steam in an atomizing nozzle; passing the effluent from the nozzle through a stripping tube operated in the spray-flow regime and having inner walls essentially parallel throughout the length of the tube, and from the stripping tube into a flash chamber; whereby solvent-swollen polymer crumb can be collected and removed from the flash chamber. Means are disclosed whereby agglomeration of polymer on the inner walls of the stripping tube and flash chamber is prevented, and whereby entrainment of polymer crumb and undue pressurization by jet pumping are avoided.
