摘要：
The invention relates to a method for the production of water absorbent polymer particles by polymerizing drops, comprising at least one monomer in a gas phase surrounding the drops, wherein the drops are produced by surrounding a first monomer solution with a second monomer solution and polymerizing the second monomer solution to a higher cross-linked polymer than the first monomer solution.
