摘要: A process for producing EP and EPDM polymers with a reduction in fouling is provided, which comprises polyemrizing ethylene, an alpha-olefin nonconjugated diolefin (if utilized) polymerization medium comprising hydrocarbon diluent at temperature of from about -50°C to 150°C the presence catalyst system (a) vanadium compound, (b) diethyl aluminum chloride, ethyl sesquichloride or dichloride (c) organo compound formula R₃Al wherein R alkyl group having 8 12 carbon atoms and, optionally, triethyl aluminum, molar ratio chloride total content being 0.7:1 0.95:1, 1.4:1 1.8:1 mols 1:10 1:50 desired conversion.
