FIELD: chemistry.
SUBSTANCE: invention relates to catalyst for obtaining ultra-high-molecular-weight polyethylene. Described is calalyst for obtaining ultra-high-molecular-weight polyethylene - UHMWRE at higher temperatures of polymerisation (≥80°C) in the medium of hydrocarbon diluent, for instance, heptane, hexane, isopeptane, containing vanadium compound on magnesium-containing carrier, which includes magnesium dichloride in amount not less than 80 wt %, and catalyst contains aluminium trichloride in amount 2.5-10 wt %.
EFFECT: increase of process productivity.
