AQUEOUS SOLUTION OF POLY(METH)ACRYLIC ACID POLYMER AND METHOD FOR PRODUCING SAME

摘要

Disclosed is a polymer (aqueous solution) exhibiting superior dispersibility and the like for inorganic matter and sufficient dispersibility over time, as well as good color tone over time, and a method for easily producing such polymers (aqueous solutions). Also disclosed is an inorganic particle slurry capable of maintaining a high pH that exhibits a high inorganic particle concentration and good viscosity and has sufficient viscosity stability over time, with a little coloration during drying, and a method for easily producing that inorganic particle slurry. Specifically disclosed is an aqueous solution or inorganic particle slurry that contains a poly(meth)acrylic acid polymer having a specific structure and a specific inorganic anion concentration that contains sulfur atoms or phosphorus atoms.
