The absorbent gel used in oilfield has bad flexibility and injection ability .Focused on the situation, this paper starting with performance and structure design, introduces inorganic material MMT to AM monomer homogeneous polymerization system , and adopts free radical solution polymerizing method to polymerize AM/MMT in-situ. Though cross experiment design and single factor optimum seeking method, compared to the system of AM/AA,this paper has prepared PAG composite absorbent gel successfully.The PAG abso...
