Abstract
A modified latex drag reducer and methods of making and using the drag reducer in order to reduce friction losses resulting from turbulent fluid flow through a conduit. Particularly, the modified latex drag reducer is formed from an initial latex which is a product of an emulsion polymerization reaction. The initial latex is then modified, preferably by admixing with at least one low HLB surfactant or at least one solvent, or both, to form a modified latex with an enhanced dissolution rate in a hydrocarbon stream over the initial latex.
