Description: This study describes the laboratory evaluation methodology of the drag reducing effect of block poly-1-octene. Poly-1-octene, synthesized in our laboratory was chosen as an object of the present study. To confirm the nature and the structure of the obtained polymer its FTIR spectrum was registered. The molecular mass was determined by viscosimetric method using an Ubellode viscosimeter, the obtained value was 5.22×106. Hydrodynamic testing of poly-1-octene solutions has been performed using a capillary rheometer of our own construction for the quantitative estimation of the polymer's drag reduction capability. We introduce criterion for a quantitative estimation of a polymer hydrodynamic drag reducing capability. This is a semi-effect concentration С1/2 that can be determined using a dependence of DR on the concentration.
