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.

Macrocyclic polyalkene homopolymers and copolymers can be formed and converted to macrocyclic polyalkanes or macrocyclic poly(alkane-co-alkene) upon hydrogenation or, when the macrocyclic polyalkene is reacted with an alkene in the presence of an olefin metathesis catalyst, to a macrocyclic poly(alkane-co-alkene) comprising vicinal C(CR2)'s. Upon hydrogenation of a macrocyclic poly(alkane-co-alkene) comprising vicinal C(CR2)-'s, macrocyclic poly(alkane)s or poly(alkane-co-alkene)s with isolated C(CR2)- groups can be provided, depending on the degree of hydrogenation. The poly(alkane-co-alkene)s with isolated C(CR2)- units can be used to form poly(macrocyclic poly(alkane-co-alkene))s, poly(macrocyclic poly(alkane))s, and/or bi-, tri-, and/or multi-macrocyclic poly(alkane-co-alkene)s or bi-, tri-, and/or multi-macrocyclic poly(alkane)s.
