Development And Performance Of A New Type Of Hydrophobically Associating Water-soluble Polymer

Based on the Acrylic acid .Diethy amine phosphorichoride as the materialto Systhesized as one-kinds of monomer ,the Based the Na2SO3 and (NH4)S2O8 as the initations with the acrylamide (AM) sythesied a series of Quaternary ammonium salt copolymer with various molecular Parameter in aqueous solution at different reaction condition sythetic temperature and monomer variation the molecular structure of copolymer was characterized b by infrared spectra and their instrinstic Viscosity-[n] and other properties.what's more ,to determine the product's properties of dilute aqueous solution so Finally . the effect of copolymer concentration ,salt concentration ,temperature and surfactant concentration on properties of copolymer have been studied. The results show that the solution viscosity will rise sharply when polymer concentration is higher than critical associating concentration( CAC) ;the effect salt on solution rhelogical property is very complicated ,the adding of NaCl will increase the viscosity of polymer semidilute solution ,but with the adding of CaCl2,it will rise first and then decline sharply ;according to the constant polymer concentration ,the decreases with the addition of SDS, MJ-18, OP-10 quickly. What's more to research the product's properties of dilute aqueous solution about the different monomer's affect to the solution and that it exist the shearing viscosity increased and the shearing viscosity decline at the different shearing rate speed. In the finally, we draw the conclusion that the copolymer has very good properties in the practical application in petroleum and other industry process.
