无机盐和十二烷基磺酸钠对丙烯酰胺──烯丙基磺酸钠共聚物粘度的影响

EFFECT OF INORGANIC SALT AND AS ON SOLUTION VISCOSITY OF COPOLYMER OF ACRYLAMIDE AND SODIAM ALLYLSULFONATE

测定了丙烯酰胺──烯丙基磺酸钠共聚物（ＰＡＳＡ）与无机盐和阴离子表面活性剂（ＡＳ）复配体系的粘度，结果表明，无机盐降低ＰＡＳＡ溶液的粘度，而在ＡＳ存在下却随ＡＳ浓度的升高溶液粘度升高．ＮａＣｌ和ＡＳ共存时，二者的共同作用，使溶液粘度呈下降趋势．

The effect of sodium dodecyl sulfonate (AS) on the viscosity of aqueous solution of copolymer of acrylamide and sodium allylsulfonate(PASA) in the presence of inorganic salts has been studied. Ti is shown that inorganic salts decrease the viscosity of PASA solution, while AS increases the Viscosity with the increase of its concentration. And the viscosity is reducing in the presence of both NaCI and AS.
