Syndiospezifische polymerisation von propylen: Neue metallocenkomplexes des typs (C13H8−nRnCR′R″C5H4)MCl2n = 0,2; R = Alkyl, Aryl, Hal; R′, R″ = H, Alkyl, Aryl; M = Zr, Hf) unter besonderer berücksichtigung verschiedener brückensubstituenten
摘要:
Eight new catalyst precursors with C-s-symmetry and of the general formula (C(13)H(8-n)R(n)CR'R '' C5H4)MCl(2) (n = 0, 2; R = Alkyl, Aryl, Hal; R', R '' = H, Alkyl, Aryl; M = Zr, Hf) have been synthesized and characterized by NMR spectroscopy, Complexes 1b-7b and 3c can be activated by MAO and are useful catalysts for the syndiospecific polymerization of propylene. First analytic results of the various polypropylene samples are discussed.
