Linear surfactant polymers, useful in waterflooding processes and as emulsion breakers, can be prepared by reacting various amines, such as hexamethylene diamine, with monofunctional pendant groups, such as propylene oxide, and then further reacting the substituted amines with a difunctional reactant, such as epichlorohydrin, to produce the polymer. The polymers may be combined with certain water-soluble metal salts to improve their efficiency as emulsion breakers and as coagulants.
