Abstract:
The invention relates to an apparatus for producing pulverulent poly(meth)acrylate, comprising a reactor for droplet polymerization having an apparatus for dropletization of a monomer solution for the preparation of the poly(meth)acrylate having 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 on the circumference of the reactor and a fluidized bed, the reactor comprising a reactor shell between the apparatus for dropletization and the gas withdrawal point and having, above the fluidized bed, a region having decreasing hydraulic diameter toward the fluidized bed and having a maximum hydraulic diameter greater than the mean hydraulic diameter of the reactor shell, and the reactor shell projecting into the region having decreasing hydraulic diameter, so as to form an annular duct between the outer wall of the reactor shell and the wall by which the region having decreasing hydraulic diameter is bounded, and the at least one gas withdrawal point being disposed in the annular duct, wherein the ratio of the horizontal area of the annular duct to the horizontal area enclosed by the reactor shell is in the range from 0.3 to 5.

Claim (Index 18):
The apparatus according to  claim 11 , wherein the ratio of the horizontal cross-sectional area ( 39 ) of the annular duct ( 21 ) to the total cross-sectional area of all gas withdrawal points ( 19 ) is in the range from 1.5 to 150.
