CATALYST COMPOSITION FOR THE OLIGOMERIZATION OF ETHYLENE, COMPRISING (I) AN AT LEAST PARTIALLY HYDROLYZED TRANSITION METAL COMPOUND, OBTAINABLE BY CONTROLLED ADDITION OF WATER TO A TRANSITION METAL COMPOUND HAVING THE GENERAL FORMULA MXm(OR?)4-m OR MXm(OOCR?)4-m, WHEREIN R? IS AN ALKYL, ALKENYL, ARYL, ARALKYL OR CYCLOALKYL GROUP, X IS HALOGEN, PREFERABLY Cl OR Br, AND m IS FROM 0 TO 4; PREFERABLY 0-3; AND (II) AN ORGANOALUMINUM COMPOUND AS A COCATALYST, WHEREIN THE MOLAR RATIO OF WATER AND TRANSITION METAL COMPOUND IS WITHIN A RANGE OF BETWEEN ABOUT (0.01-3): 1; A PROCESS FOR OLIGOMERIZATION OF ETHYLENE AND A METHOD FOR PREPARING THE CATALYST COMPOSITION. |
