METHOD FOR PRODUCING WATER-ABSORBENT POLYMER PARTICLES WITH A HIGHER PERMEABILITY BY POLYMERISING DROPLETS OF A MONOMER SOLUTION |
| 摘要 |
<p>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 150μm.</p> |
