ABSTRACT:
In order to achieve good results during the continuous recovery of organic polymers from solutions or emulsions thereof, even if there are irregularities due to variations in operation, and to ensure a minimum residual content of solvent in the polymer, a two-component nozzle is used, from whose inner duct the solution or emulsion is injected at an angle .beta. to the nozzle axis and from whose outer duct a vapor jet issues at an angle .alpha. which is between 1.degree. and 90.degree. greater than the angle .beta., the vapor jet breaking the jet of solution or emulsion into many small particles and wherein injection takes place in a vessel which is filled with a liquid which is immiscible with the solution or emulsion, in particular water.
