Inverse microemulsions having a Standard Viscosity of at least about 3.3 cps are disclosed which comprise an aqueous phase of dispersed micelles containing water and an (alk)acrylamide-based polymer substituted with at least 1 mole percent of quaternized tertiary aminomethyl groups, wherein said microemulsion is derived from a microemulsion containing greater than about 20 percent, by weight, and less than about 40 percent, by weight, of aqueous phase polymer solids, based on said microemulsion. A method of making said microemulsions and use thereof to dewater dispersions of suspended solids are also taught.

High standard viscosity quaternary Mannich microemulsions

Inverse microemulsions are disclosed wherein the dispersed micelles containing water and an (alk)acrylamide-based polymer substituted with at least one mole percent of quaternized tertiary aminomethyl groups i.e. the aqueous phase, contain from about 20 percent to about 40 percent, by weight, of polymer solids and the microemulsion has a Standard Viscosity of at least about 3.3 cps. A method of making said microemulsions and use thereof to dewater dispersions of suspended solids are also taught.

High standard viscosity quaternary mannich microemulsions

A method for increasing the standard viscosity (SV) of an emulsion, and the composition of the emulsion resulting thereby is provided. Also, an alternative method for increasing the standard viscosity as well as increasing the shelf life, i.e., SV stability, of quaternary mannich microemulsion is provided.

Quaternary mannich polymer microemulsion (QMM) with rapid standard

Quaternary dialkylaminomethyl polymers derived from (alk)acrylamide and about 1 to about 15 mole percent ethylenically unsaturated anionic comonomer wherein the resulting ampholytic polymer has a standard viscosity of at least about 2.1 cps are disclosed. Processes for the preparation of these polymers and their use in flocculating suspended material in a variety of aqueous dispersions are also disclosed.

Ampholytic polymers and polymeric microemulsions

Quatemary dialkylaminomethyl polymers derived from (alk)acrylamide and about 1 to about 15 mole percent ethylenically unsaturated anionic comonomer wherein the resulting ampholytic polymer has a standard viscosity of at least about 2.1 cps am disclosed. Processes for the preparation of these polymers and their use in flocculating suspended material in a variety of aqueous dispersions are also disclosed.
