摘要:
An apparatus for production of pulverulent polymers having a reactor for droplet polymerization with an apparatus for dropletization of a monomer solution for the preparation of the polymer. The apparatus for dropletization has holes through which the monomer solution is introduced, an addition point for a gas above the apparatus for dropletization, at least one gas withdrawal point at the periphery of the reactor and a fluidized bed, wherein at least one of the following is fulfilled: an apparatus for increasing turbulence in the gas flow is disposed in the region of the apparatus for dropletization of the monomer solution, an apparatus for increasing turbulence in the gas flow is disposed in the region of the addition point for the gas, the addition point for gas is configured such that elevated turbulence is generated. A process for producing pulverulent polymers, in which an increase in flow turbulence in the gas flow in the region of the apparatus for dropletization also is disclosed.
