Aqueous solution composition with variable viscosity change pattern under shear

摘要

It is an object of the present invention to provide an aqueous solution composition having a variable change pattern of viscosity under a certain shear. The following components (A) and (B), (A) water-soluble ionic polymer (B) ions having an ionic group density of 2 meq / g or more and a weight average molecular weight of 100,000 to 10 million A functional group density of 1 meq / g or less, a weight average molecular weight of 1,000,000 to 10,000,000, and a water-soluble ionic polymer having an ionic property opposite to that of (A). The a / b ratio is 0.8 イ オ ン a / b の 12, where a meq is the ion equivalent of the derived ionic group and b meq is the ion equivalent of the ionic group derived from the component (B). The aqueous solution composition was found to have a variable viscosity change pattern under shear. [Selection figure] None
