ABSTRACT:
Easily dispersible anionic water-soluble polymers are disclosed which are prepared by lightly treating particulate water-soluble polymer with a water-soluble aluminum salt and an aluminum chelant. Rate of hydration is retarded when the particles are added to aqueous media, allowing the particles to be dispersed completely before their surfaces hydrate sufficiently to gel and prevent complete dissolution.
