Abstract
PURPOSE: The titled material that is made by integrally adhering the supporting layer to the swelling layer consisting of an elastic high-polymer material and another high-molecular material swelling with water, thus being used as a sealing material with long-lasting water-stop property, because of its high physical strength even when swelled.
CONSTITUTION: (A) The expanding layer that consists of an elastic high-polymer material, preferably hydrophobic, such as natural rubber or butyl rubber, and of a high-polymer material swelling with water, which is included in the elastic polymer, preferably a block and/or graft copolymer having the linkages of hydrophobic segment-hydrophilic segment-hydrophobic segment, is integrally laminated with at least one supporting layer of (B) a high-molecular-weight material causing no reduction in strength even when coming into contact with water such as polyvinyl chloride or polyethylene.
