More Information
Summary:A drag reducing agent has a core comprising a polyolefin; and a temporary container encapsulating the core. The temporary container contains a container material, which includes an ethylene vinyl acetate copolymer, an ethylene vinyl alcohol copolymer, a polyvinylpyrrolidone, an ethylene vinylpyrrolidone copolymer, a vinylpyrrolidone vinyl acetate copolymer, a polyvinyl acetate, a polyvinyl alcohol, a polyethylene oxide, a polyethylene glycol, polyvinylidene chloride, a polysaccharide or its derivative, or a combination comprising at least one of the foregoing. A largest dimension of the drag reducing agent is greater than about 1,000 microns.
