An apparatus for addition of droplets of a monomer solution for production of poly(meth)acrylate to a reactor for droplet polymerization, comprising at least one channel or a dropletizer head having, at its base, holes through which the solution is dropletized into the reactor, at least one of the following features being fulfilled: (a) the ratio of the area covered by the channels or the dropletizer head in the reactor relative to the area which is defined by the circumference of a line along the outermost holes is less than 50%, (b) the number of holes relative to the area which is defined by the circumference of a line along the outermost holes is within a range from 100 to 1000 holes/m2.
