3-Sulfopropyl acrylate, potassium salt (SPAK) is a functional acrylic acid monomer useful in the synthesis of new generation of super water absorbent, superporous, polymer hydrogels. SPAK mainly used to improve hydrogel properties; e.g., stabilize waterborne acrylic dispersion, adhesion, ion exchange resin and poly-electrolytes. SPAK also helps improve antistatic properties of polymers.
