Abstract
An apparatus for introducing droplets of a monomer solution for production of poly(meth)acrylate into a reactor for droplet polymerization, comprising at least one channel or a dropletizer head, the channel or the dropletizer head being sealed at its base by a dropletizer plate, the dropletizer plate having holes through which the monomer solution is introduced into the reactor, and the dropletizer plate being configured such that holes that, in an axially symmetric dropletizer plate or in an annular dropletizer plate or in one configured as a ring segment, are not on a center line of the dropletizer plate or, in the case of a circular dropletizer plate, are not at the center of the dropletizer plate are aligned such that monomer solution is introduced through the holes into the reactor at an angle to the vertical, and the holes in the case of a radial alignment of axially symmetric dropletizer plates being aligned such that the angle at which the monomer solution is introduced into the reactor decreases in the direction of the axis of the reactor and, in the case of dropletizer plates arranged parallel to one another or of concentrically arranged dropletizer plates, each being aligned on a line parallel to the center line or line running concentrically about the center, such that the angle at which the monomer solution is introduced into the reactor is constant.
