Abstract

original image

Long chain running: The polymerization performance of guanidinato titanium(IV) olefin catalysts is tuned by monodentate ancillary ligands. Polymerization activities of up to 8800 kgPE molcat.−1 h−1 bar−1 together with molecular weights of 2500 kg mol−1 were observed (see figure; d-MAO=dry methylalumoxane). Ligand transfer of the additional donor ligands has to be avoided.
