A method of making an absorbent binder composition includes combining a first aqueous monomer solution including a reducing polymerization initiator with a second aqueous monomer solution including an oxidizing polymerization initiator to form a binder composition having post application, moisture-induced crosslinking capability. The first aqueous monomer solution includes a monoethylenically unsaturated monomer and an ethylenically unsaturated monomer that contains an alkoxysilane functionality. The second aqueous monomer solution includes a monoethylenically unsaturated monomer. The monoethylenically unsaturated monomer included in the first and second aqueous monomer solutions may be carboxylic, sulphonic, or phosphoric acids or salts or a combination thereof. The ethylenically unsaturated monomer may be an acrylate or methacrylate. Crosslinking of the resulting binder composition is induced by removal of water. The polymerization of the monomer solutions to form an absorbent binder composition may be carried out in about 100 minutes or less.
