The objective of the present study is to improve the behavior of sulfonated polyacrylamide (SPA) by adding Laponite and/or chromium(III) with a focus on enhanced oil recovery applications. The resultant systems are weak nanocomposite hydrogels which are subjected to rheological, thermal stability and adsorption tests. The interactions between ingredients of the hydrogel are investigated by
