Abstract
A process in which a mixture is agitated in a substantially oxygen-free environment to produce an agitated emulsion. The mixture comprises water, one or more surfactants, a hydrate inhibitor, and a monomer. The monomer is then polymerized in the emulsion using an initiator and a catalyst to form a hydrate inhibited latex drag reducer.
