Abstract: The present invention further relates to a process to make a superabsorbent polymer comprising the steps of a) preparing a neutralized monomer solution comprising a polymerizable monomer selected from unsaturated acid groups-containing monomers, ethylenically unsaturated carboxylic acid anhydride, salts, or derivatives thereof and a caustic agent selection from an alkali agent, wherein the polymerizable monomer is neutralized to from about 50mol% to about 85mol%; b) forming a crosslinker monomer mixture by adding an internal crosslinker composition to the neutralized monomer solution wherein the internal crosslinking composition is the reaction product of a stoichiometric excess of amine with a glycidyl compound, wherein the internal crosslinker composition has a residual amount of glycidyl compounds of less than about 500ppm based on the mass of the internal crosslinker composition; and c) polymerizing the crosslinker monomer mixture to make a superabsorbent polymer.
