CROSS-LINKED POLYMER COMPOSITION SWELLING IN WATER AND PROCESS FOR PRODUCING THE SAME |
摘要 |
<p>The present invention has an object to provide a novel water-swellable crosslinked polymer composition which exhibits excellent saltwater absorption speed and capacity under a load. This object can be achieved in the case where, in a water-swellable crosslinked polymer composition comprising a blend of water-swellable crosslinked polymer particles of basicity in water and water-swellable crosslinked polymer particles of acidity in water, the water-swellable crosslinked polymer particles of basicity in water are unified with the water-swellable crosslinked polymer particles of acidity in water through ionic bondings in a state where water is present between the particles, wherein the ionic bondings are formed in a state where water is present between the particles by neutralization of at least part of acid groups of the water-swellable crosslinked polymer particles of acidity in water with the water-swellable crosslinked polymer particles of basicity in water. <IMAGE></p> |
