Abstract: A process for preparing water-absorbing polymer beads by polymerizing droplets comprising at least one monomer in a gas phase surrounding the droplets, the droplets being obtained by enveloping a first monomer solution with a second monomer solution and polymerizing the second monomer solution and polymerizing to give a more highly crosslinked polymer than the first monomer solution.

Abstract: The invention relates to a process for preparing polymers from monomers and/or oligomers by adding a liquid comprising the monomers and/or oligomers dropwise to a continuous liquid phase in a reactor, the continuous liquid phase being immiscible with the liquid comprising the monomers and/or oligomers, and the monomers and/or oligomers reacting in the continuous liquid phase to give the polymer. The liquid comprising the monomers and/or oligomers is shaped to droplets outside the continuous liquid phase, which are subsequently introduced into the continuous liquid phase. The invention further relates to a reactor for performing the process, comprising a tube through which a continuous liquid phase flows, and means of generating droplets, the means of generating droplets being arranged such that the droplets are generated outside the continuous liquid phase and then introduced into the continuous liquid phase.
