Patent ID: 6849685

Claim:
A method of making an absorbent binder composition comprising: forming a first aqueous monomer solution including a monoethylenically unsaturated monomer selected from the group consisting of carboxylic acid salts, sulphonic acid salts, phosphoric acid salts, and combinations thereof; an ethylenically unsaturated monomer including an acrylate or a methacrylate that contains an alkoxysilane functionality; and a reducing polymerization initiator; forming a second aqueous monomer solution including a monoethylenically unsaturated monomer selected from the group consisting of carboxylic acid salts, sulphonic acid salts, phosphoric acid salts, and combinations thereof; and an oxidizing polymerization initiator; combining the first aqueous monomer solution with the second aqueous monomer solution wherein the reducing polymerization initiator reacts with the oxidizing polymerization initiator to form a binder composition; and inducing crosslinking of the binder composition by removal of water.
