A polymer composition has been developed that comprising an oil-in-water emulsion comprising an aqueous phase comprising water and an emulsifying surfactant having a cloud point of less than 80° C. and a hydrophilic-lipophilic balance (HLB) of greater than or equal to 8, and an oil phase comprising a high molecular weight oil-soluble polymer, wherein the oil-soluble polymer comprises a copolymer derived from reaction of a hydrophobic monomer and an ionizable monomer in a weight ratio from about 999:1 to about 80:20. Methods of using the compositions for drag reduction and corrosion inhibition are also disclosed.

Emulsion polymers and methods for improving pumpability

A continuous inverse emulsion polymerization process may involve combining an aqueous monomer composition with an oil composition in a premix vessel and allowing the aqueous monomer composition to interact with the oil composition in the premix vessel for a period of time effective to form a stable pre-emulsion. The stable pre-emulsion may then be homogenized to form a homogenized emulsion that is then polymerized to form a water-in-oil inverse emulsion polymer. By forming a stable pre-emulsion that is then homogenized, the resulting water-in-oil inverse emulsion polymer may have uniform and consistent polymer size distribution.
