摘　　要：本文主要研究了含有 NaCl 和 R_4OH(正丁醇)的体系中,R_(12)SO_3Na(十二烷基磺酸钠)对HPAM(部分水解聚丙烯酰胺)溶液粘度的影响。发现 NaCl 和 R_4OH 的存在均使 HPAM 溶液粘度降低,加入 R_(12)SO_3Na 可使之进一步降低。但是 NaCl-R_4OH-R_(12)SO_3Na 混合液降低 HPAM 溶液粘度的效能,低于它们单独存在时的作用之和。R_(12)SO_3Na 对 HPAM 溶液粘度的影响规律,类似于无机盐。The effect of sodium dodecyl sulfonate(R_(12)SO_3Na) on the viscosity of aqueous solu- tions of partially hydrolysed polyacrylamide (HPAM) in the presence of NaCl and n-butyl alcohol (R_4OH) has been studied.It is shown that the solution viscosity of HPAM decreases at the presence of both NaCl and R_4OH and a further decrease is observed with adding R_(12)SO_3Na,though these three chemicals do not possess additive property in their effect on the solution viscosity of HPAM.The effect of R_(12)SO_3Na on HPAM solutlon viscosity is similar in its tendency to that of inorganic salts.The viscosity data of HPAM are presented in terms of characteristic viscosities,[η],together with root mean square end-to-end distances,<r^2>^(1/2),of polymer coils in dilute aqueous solution.
