Characterization of α-olefin polymer DRA(drag reduction agent) prepared by solution polymerization under different conditions was carried out by loop system. The results showed Drag reduction was affected greatly by the solvent used in the synthesis. When the solvent was Cyclohexane, drag reduction rate was up to 62.3%, but 50.33% when the solvent was Hexane; DR% of three samples droped rapidly with increasing shearing time. On those bases, the effects of the polymer characteristics on drag reduction were studied further. Particle density and concentration were obtained through viscosimetry. The results showed when characteristic viscosity was smaller, the density was higher, the concentration was lower, and the molecular mass was higher, the drag reduction result was better. Otherwise, drag reduction result was worse.
