ABSTRACT:
A particulate water-soluble polymer is dispersed in a liquid medium comprised of low molecular weight polyethylene glycol, water and high molecular weight polyethylene glycol in amounts sufficient to impart stability to the dispersion. The dispersion is used in a process for dispersing the water-soluble polymer into aqueous solutions, such as latex paints, comprising preparing the dispersion and feeding the dispersion into the aqueous solution. The dispersion has excellent dispersion stability and fluidity, and is easier to handle and has a higher dissolution rate than the dry powder (particulate) form of the water-soluble polymer.
