Abstract:
A catalyst system comprising a half-sandwich chromium complex, an activator support and an optional cocatalyst. A compound of formula Cp′Cr(Cl)2(Ln), where Cp′ is η5—C5H4CH2CH2CH═CH2 and Ln is pyridine, THF or diethylether. A compound of formula Cp″Cr(Cl)2(Ln), where Cp″ is η5—C5H4C(Me)2CH2CH2CH═CH2 and Ln is pyridine, THF or diethylether.
