| Abstract: | The amphoteric polyacrylamide for the thickener of fracturing fluid is prepared using inverse phase suspension polymerization and redox initiation system.The chemical structure of the product is characterized with FT-IR.It is shown that the relative molecular mass of the product reaches to 5.28×106 under the optimum conditions of the dosage of initiator of 0.8% (relative to monomer),the dosage of emulsifier of 10% (relative to oil phase),the mass ratio of oil to water of 1.4∶1,the reaction temperature of 40 ℃,and the substance amount ratio of AM,DMC to AA of 1∶0.6∶0.3. |
