The water-soluble tripolymer of maleic anhydride(MA), sodium allylsufonate(SAS)and acrylamide(AM) was prepared with water as solvent and persulfate as initiator.
Self-preparation polymerizable macromolecular surfactant HTP and acrylate monomer were used to prepare the amphiphilic polymer by soap-free microemulsion pentamer copolymerization.
