An investigation has been undertaken by use of ESCA in the characterization of the central metal(Zr)of dichlorozirconocene/methylaluminoxane homogeneous olefin Polymerization catalyst.The change of electron density shown by a shift in ESCA signals (181.8- 182.7eV) indicates that the catalytic species are 'canon-like'. Within the range of detecting sensitivity of ESCA spectrometer , only a part of the new catalytic derivative was formed. The influence of complexion time and Al Zr ratio on the formation of the catalytic zirconocene cation has also been investigated.
