Beschreibung
Zusammenfassung:	A catalyst system comprising: (a) one or more bisarylimino pyridine iron or cobalt catalysts; (b) a first co-catalyst compound which is selected from aluminium alkyls, aluminoxanes, and mixtures thereof; and (c) a second co-catalyst compound which comprises one or more compounds of the formula ZnR'2 wherein each R', which may be the same or different, is selected from hydrogen, optionally substituted C1-C20 hydrocarbyl, phenyl, Cl, Br, I, SR'', NR''2, OH, OR'', CN, NC wherein R'', which within the same molecule may the same or different, is C1-C20 hydrocarbyl.
