Beschreibung
Zusammenfassung:	FIELD: polymerization catalysts. ^ SUBSTANCE: catalysts, which may, in particular, be used in production of cis-1,4-homopolymers and cis-1,4-copolymers in synthetic rubber industry, are prepared by reaction of rare-earth element compound and conjugated diene in hydrocarbon solvent with preliminarily formed complex, the latter being prepared by chlorination agent-alkylation agent-Lewis base triple interaction. ^ EFFECT: increased activity and stereoselectivity of catalyst. ^ 10 cl, 1 tbl, 20 ex
