Abstract

This invention concerns a method for precipitating polymers from a liquid using at least one precipitant fluid, including a feed line, a nozzle plate having at least one outlet orifice for a polymer containing fluid with the outlet orifice communicating with the feed line, at least one nozzle for at least one precipitant fluid, the axis of which is arranged approximately perpendicularly to the axis of the outlet orifice, a precipitation chamber positioned on the side of the nozzle plate wherein at least one nozzle for at least one precipitant fluid is located, a discharge line for discharging a mixture which contains the precipitated polymer and a degassing chamber which is connected to the discharge line.
