Synthesis Of Polyacrylamide-Based Hydrogel Using Inverse Pickering Emulsion Polymerization

High molecular-weight polyacrylamide is used in tertiary oil recovery, drag reduction and drilling fluids. The main methods of AAm-based polymer synthesis are radical polymerizationin solution, inverse emulsion, and suspension. When particles instead of surfactant molecules are used to stabilize theemulsion ,the term Pickering emulsion is commonly used. Recently this method have been studied to produce acrylamide-base hydrogels. The purpose of this study is toproduce acrylamide gel particles with a controlled size for enhanced oil recovery(EOR) applications.
