Abstract
1. Способ получения антитурбулентной присадки к органическим средам для снижения гидродинамического сопротивления при их транспортировке путем полимеризации поли-альфа-олефинов в массе или среде органического растворителя с использованием катализаторов Циглера-Натта при перемешивании с последующим выделением полимера из раствора и изготовлением дисперсии в среде органического вещества, не растворяющего поли-альфа-олефин, отличающийся тем, что полимеризация осуществляется при перемешивании с интенсивностью, обеспечивающей для исходной полимеризационной шихты соблюдение центробежного критерия Рейнольдса в диапазоне 400-2700, температуре 0-30°С, с получением полимера с характеристической вязкостью не менее 1,7 м/кг.2. Способ по п. 1, отличающийся тем, что при проведении полимеризации альфа-олефинов в массе конверсия мономеров в полимер составляет (5-15) %.3. Способ по п. 1, отличающийся тем, что при полимеризации альфа-олефинов в органическом растворителе конверсия мономеров в полимер составляет (85-99) %.1. A method of obtaining an anti-turbulent additive to organic media to reduce hydrodynamic resistance during their transportation by polymerization of poly-alpha-olefins in bulk or in an organic solvent medium using Ziegler-Natta catalysts with stirring, followed by isolation of the polymer from the solution and making a dispersion in the organic medium that does not dissolve poly-alpha-olefin, characterized in that the polymerization is carried out with stirring with an intensity that provides for ref one polymerization charge, the observance of the centrifugal Reynolds criterion in the range of 400-2700, temperature 0-30 ° C, to obtain a polymer with a characteristic viscosity of at least 1.7 m / kg. 2. The method according to claim 1, characterized in that during the polymerization of alpha-olefins in bulk, the conversion of monomers to polymer is (5-15)%. 3. The method according to claim 1, characterized in that during the polymerization of alpha-olefins in an organic solvent, the conversion of monomers to a polymer is (85-99)%.
