Abstract
One embodiment of the present invention is a method for synthesizing superabsorbent polyacrylate polymers comprising the steps of providing an acrylate monomer, a multifunctional monomer, and free radical initiator in the absence of a solvent; mixing the acrylate monomer, multifunctional monomer, and free radical initiator to create a solvent free solution; and subjecting the solvent free solution to radiation to create a cross-linked polymer. The product created by this method is also a part of the present invention.
