    摘要: Latex drag reducers and systems for delivering latex drag reducers are disclosed. The latex drag reducers comprise a polymer that is formed via an emulsion polymerization reaction dispersed in a continuous phase and can undergo subsequent modification in order to increase the solubility of the polymer in hydrocarbons. The polymers generally present a particle size of less than about 1000 nm and are suitable for delivery to a subsea flowline via a small diameter conduit of an umbilical line without an unacceptable level of pressure drop or plugging of the conduit.
