Abstract:
End‐group analyses of the oligo‐ and polypropylenes produced with bis(phenoxy‐imine) Zr and Hf complexes with methylaluminoxane (MAO) indicate that the polymerization is initiated by two consecutive 1,2‐insertions and is terminated by a β ‐H transfer following a 2,1‐insertion. Our data indicate that chain propagation occurs with prevailing 1,2‐regiochemistry but with considerable regioerrors, and with virtually no stereoselectivity. The polymerization of propylene mediated by bis(phenoxy‐imine) Zr and Hf complexes with MAO. magnified image The polymerization of propylene mediated by bis(phenoxy‐imine) Zr and Hf complexes with MAO.
