Abstract
The present disclosure provides a drag reducing agent. In an embodiment, the drag reducing agent includes a polymer and a liquid carrier. The polymer is composed of one or more C6-C14 α-olefin monomers. The polymer includes a residual amount of zirconium. The polymer has an absolute weight average molecular weight (Mw(Abs)) greater than 1,300,000 g/mol and a (Mw(Abs)/Mn(Abs) from 1.3 to 3.0.
Claims8
A drag reducing agent comprising:
- from 10 wt % to 80 wt % of a polymer consisting of (i) one or more C6-C14 α-olefin monomers, and (ii) a residual amount of a component selected from the group consisting of zirconium, germanium, boron, and combinations thereof, the polymer having an absolute weight average molecular weight (Mw(Abs) greater than 1,300,000 g/mol and a Mw(Abs)/Mn(Abs) from 1.3 to 3.0;
- from 20 wt % to 90 wt % of a liquid carrier;
- and
- the drag reducing agent has a viscosity at 100° C. from 2.9014*10+05 m-Pas to 3.573*10+07 m-Pas.
