Method for producing water-absorbing polymer particles having high permeability of swollen gel bed, fast swelling speed and high centrifugal retention capacity
Aqueous monomer in a polymerization reactor having at least two shafts (kneaders) rotating in parallel to the axis of water-absorbing polymer particles having a high swelling speed and a high centrifugal retention capacity simultaneously with high permeability of the swollen gel bed Production process by solution polymerization, followed by high temperature extrusion and post surface crosslinking by heat.膨潤したゲル床の高い透過性と同時に、速い膨潤速度、かつ高い遠心分離保持容量を有する吸水性ポリマー粒子の、軸平行に回転する少なくとも2つのシャフト(混練機)を有する重合反応器における水性モノマー溶液の重合、それに続く高温での押し出し、および熱による表面後架橋による製造方法。
