## Abstract

The invention relates to agents reducing the hydrodynamic drag of a turbulent flow of petroleum products in the process of transportation in pipelines. The technical result of the solution involves the preservation of the polymer structure so that the polymer is more effective in reducing the hydrodynamic drag, grinding costs in the production of the DRA, the aggregation of the DRA while reducing the amount of the separating agent and the need to inject a smaller amount of the reagent to reduce the hydrodynamic drag. The specified technical result is produced due to the development of a reagent for reducing the hydrodynamic drag of hydrocarbon liquids in pipelines, which consists of the first and the second component, in which case the first component comprises the particles of polyalphaolefin or polyacrylate, the second component is an anti-agglomerating agent.
