Abstract
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.
