ABSTRACT:
This invention is directed to coated water-swellable materials, typically solid, particulate, water-swellable materials, i.e. materials that comprise hydrogel-forming polymers, whereof at least a part is coated with a coating, which substantially does not break when the polymers swell, as set out in the method herein. Said coating is present at a level of at least 1% by weight of the water-swellable material.The coating comprises preferably an elastomeric polymeric material. The invention also relates products, e.g., disposable absorbent articles, comprising such coated water-swellable material.
