Mar 21, 2017

With the rapid development of the nationaleconomy, the necessity of water treatment is increasingly prominent,flocculation technology is to improve water treatment efficiency of the mostcommonly used technology. Especially as the flocculant high molecular weightpolyacrylic acid sodium, has become the subject of domestic and foreignresearchers competing research. In this paper, the emulsion polymerization ofacrylic acid and its comonomer is studied. The choice of emulsifier, the choiceof initiator system, the amount of polymerization initiator, the temperature ofpolymerization and the time of polymerization are discussed. The degree ofneutralization of the system, the type and proportion of comonomer, the totalmonomer concentration, the type of non-polar solvents and mix. Should continueto develop and improve the existing polymerization methods and processconditions, the polymerization mechanism and the polymerization kinetics ofin-depth study. Develop new and efficient polymerization initiation systems,explore high-performance retarders, and explore more efficient polymerizationmethods. To study how to improve the relative molecular mass to optimize itsperformance, to study the application of high solid content polymerization andnew technology in each polymerization method, to develop polymer typeemulsifier. To explore the reverse microemulsion polymerization method, so thatthe sodium polyacrylate from the laboratory research to industrialization,industrialization into. With the vigorous development of economic construction,science and technology advances, the polymer water-soluble polymers, especiallypolyacrylic acid product performance requirements will become increasinglyhigh, its bound to have a broader development prospects.
