Aqueous dispersions of cationic water-soluble polymers are provided, as well as processes for making and methods of using the same.

Aqueous dispersions

Aqueous dispersions of cationic water-soluble polymers are provided, as well as processes for making and methods of using the same. The cationic polymers contain anionic recurring units in amounts that encourage the formation of the aqueous dispersion and/or advantageously reduce the bulk viscosity of the aqueous dispersion.

Compositions of precipitated anionic polymers containing mixtures of certain salts as well as processes for making and using the same are disclosed.

Anionic water-soluble polymer precipitation in salt solution

Compositions of precipitated cationic polymers containing mixtures of certain salts as well as processes for making and using the same are disclosed.

Cationic water-soluble polymer precipitation in salt solutions

Process for preparing aqueous dispersions

Compositions of precipitated anionic polymers containing mixtures of cationic organic salts and kosmotropic salts as well as processes for making and using the same to condition soil are disclosed.

Processes for conditioning soil with anionic water-soluble polymers

Stable compositions as flocculants comprising a blend of at least two inverse emulsions, at least one of which is a polymeric microemulsion, provide effective flocculating performance over time. Methods for preparing stable emulsion blends use stabilizing amounts of aldehyde scavenger.
