Abstract

A process of making the flexible superabsorbent binder polymer composition includes preparing a preneutralized monomer solution having at least about 40 mol % degree of neutralization, preparing a monomer solution including monoethylenically unsaturated monomers, one of which includes an alkyloxysilane functionality, preparing initiator system solutions and adding the solutions to the monomer solution, mixing the foregoing solutions into a polymerization solution, cooling the polymerization solution, and post neutralizing the polymer.
