A solution polymerization process for producing ethylene-based polymer includes introducing ethylene monomer, hydrocarbon solvent, and Ziegler-Natta catalyst into an entrance of a solution polymerization reactor. An ethylene-based polymer is produced by solution polymerizing the ethylene monomer in hydrocarbon solvent. Subsequently, a catalyst deactivator is introduced into the exit of the solution polymerization reactor, thereby producing hydrochloric acid byproduct. The catalyst deactivator includes long chain carboxylate and at least one cation selected from Groups 1, 2, and 12 of the IUPAC periodic table, with the exception of calcium. The catalyst deactivator reduces the effectiveness of the Ziegler-Natta catalyst and neutralizes the hydrochloric acid by forming a chloride salt other than calcium chloride.

The invention relates to inorganic and polymeric reagents and namely to pipeline transfer of petroleum and petroleum products. The method of production of a reagent for reduction of hydrodynamic resistance of liquid hydrocarbon flow in pipelines includes polymerization of C6-C14 alpha-olefins over catalyst and catalyst activator. Polymerization of C6-C14 alpha-olefins is conducted in the monomer medium with addition from 0.1 to 5 w/w of a saturated alicyclic hydrocarbon of C8-C32 composition and a saturated aliphatic hydrocarbon of C6-C18 composition subject to conversion of monomers from 96.0 to 99.5 w/w, using microspheric titanium trichloride as a catalyst, and a mixture of diethylaluminum chloride and triisobutylaluminum with weight ratio from 1:10 to 10:1 as a catalyst activator. Then a polymer with molecular weight more than 10.sup.7 atomic mass unit with narrow molecular weight distribution not more than 1.5 with the set ratio of components is produced. Then the polymer is being ground.
