A process for preparing water-absorbing polymer beads with high permeability by polymerizing droplets of a monomer solution in a gas phase surrounding the droplets, wherein a water-insoluble inorganic salt is suspended in the monomer solution and the polymer beads have a mean diameter of at least 150 μm.本發明係關於一種藉由在環繞單體溶液微滴之氣相中聚合該等單體溶液微滴而製備具有高滲透性吸水聚合物珠粒之方法,其中一水不溶無機鹽懸浮於該單體溶液中且該等聚合物珠粒具有至少150微米之平均直徑。
