A method of preparation of an absorbent composite in which an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization is applied to a substrate, and the monomer is polymerized while the substrate to which the aqueous solution is applied is, on both the sides, held in contact with polymerization-inert surfaces facing each other. A continuous manufacturing method includes the sequential steps of continuously passing a substrate through (1) a region applying to the substrate an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into an absorbent polymer by polymerization, and (2) a region of polymerizing the monomer while maintaining the substrate, on both the sides, in contact with polymerization-inert surfaces facing each other.
A method of manufacturing a water absorbent composite comprising applying to a substrate an aqueous solution containing a water-soluble radical polymerization initiator and a water-soluble ethylenically unsaturated monomer which can be converted into a water absorbent polymer by polymerization, and polymerizing said monomer under a condition that two sides of the substrate applied with said aqueous solution are held in contact against polymerization-inert surfaces which face each other.
