FIELD: chemical industry, more particularly preparation of anhydrous lanthanoid halides. SUBSTANCE: organic lanthanoid derivative includes lanthanoid carboxylates or alcoholates soluble in hydrocarbons. Halogen-containing compound is selected from group consisting of halides of III, IV and V group elements and alkylaluminium halides. The resulting lanthanoid halides have catalyst activity and are useful as catalysts of polymerization of unsaturated hydrocarbons. EFFECT: more efficient preparation method. 13 ex
