FIELD: chemistry of polymers. SUBSTANCE: invention relates to a method of synthesis of alpha-olefinic high-molecular polymers in solution by polymerization of ethylene or a mixture of ethylene and at least one of higher C3-C12-olefins in the presence of coordination catalyst consisting of two components: the first component has Ti, Mg, Al and the second one has a mixture of alkylaluminium and alkoxyalkylaluminium. Process is carried out at heating to 180-320 C. Formation of the first and the second component and their mixing are carried out at temperature below 30 C. Method ensures to use catalysts exhibiting the increased activity at temperature above 180 C. EFFECT: improved method of synthesis. 9 cl, 4 tbl, 3 ex
