Polyacrylamide ( PAM ) is a a good linear polymer of a water-soluble polymer . With a wide range of applications in the petroleum , mining, water treatment, pulp and paper, textiles, mining and metallurgical industry , sugar industry , aquaculture , construction , pharmaceutical and other industries . Because of its good thermal stability and excellent thickening , flocculation , sedimentation , tackifier , purification and many other features , it is very active in its research . This paper first introduces polyacrylamide classification , properties and applications , discusses the synthetic polyacrylamide aqueous solution polymerization , emulsion polymerization, inverse microemulsion polymerization method , and gave details of a variety of theoretical studies of the micro- emulsion , mechanism of acrylamide polymerization initiator classification . The reverse microemulsion polymer has a relatively high molecular weight, viscosity of the reaction system is low , so that the inverse microemulsion polymerization prepared polyacrylamide become a hot research . The subject of this study using the method of inverse microemulsion polymerization , the choice of ammonium sulfate - sodium bisulfite , azobisisobutyronitrile , ammonium persulfate initiator three - sodium bisulfite and azo-bis- isobutyronitrile composite triggered agent, inverse microemulsion polymerization , the impact of different types of initiator relative molecular mass of polyacrylamide microemulsion polymerization different initiator experimental conditions . Different initiator synthesized PAM optimum reaction conditions were obtained by orthogonal experimental design method . Polyacrylamide synthesized under the optimal reaction conditions , molecular weight , solubility , FT - IR , SEM and other tests . The results show that : under the best conditions , the compound initiators , initiator was prepared by the PAM molecular weight of 1.44 × 107 , its solubility is also good as in the previous two . By comparing the different trigger the PAM agent under the conditions obtained infrared spectroscopy and scanning electron micrographs found under in initiator different conditions , the composition of the synthetic PAM structure and appearance profiles are different .
