Abstract
Hydrocarbon streams, such as crude oil streams, may have reduced drag when an effective amount to reduce drag of a drag reducing composition is added to a liquid hydrocarbon, where the drag reducing composition includes a drag reducing latex comprising at least one plasticizer in an amount effective to improve the ability to pump the latex into a hydrocarbon composition or stream with assured flow of the latex. Latex formulations are known to cause agglomerated particles during pumping operations, and the agglomerated hard particles tend to plug check valves in injection pump equipment, but the inclusion of at least one plasticizer reduces or prevents such problems.
