  A catalyst component for polyolefin production catalysts comprising a metallocene compound represented by general formula (1) (symbols have the meanings as described in the specification), polyolefin production catalyst containing the component, and method for producing polyolefin with the catalyst are provided. Use of a catalyst containing the novel metallocene compound as a catalyst component of the invention in polymerization of .alpha.-olefin, particularly propylene, enables one to prepare high rigid, high melting point isotactic polypropylene useful as an industrial material for automobiles and the like, more specifically isotactic polypropylene having highly controlled stereoregulartity and regioregularity, particularly the one having a high regioregularity that has been difficult to achieve with conventional metallocene catalysts. ##STR1##

  The synthesis of a series of indenyl amido titanium dimethyl complexes, by means of the direct synthesis from the ligand, a 2-fold excess of MeLi, and TiCl4 is reported. The H-1 NMR spectra of the complexes show a quartet structure for the metal-bound methyl groups, due to through-metal proton-proton coupling. Coupling of Ti-methyl protons with protons on the Cp ring is also revealed by COSY 2D-NMR. The performance of the Ti complexes in propylene polymerization, including [Me2Si(Me4C5)(t-BuN)]TiMe2 (1-TiMe2), [Me2Si(Ind)(t-BuN)]TiMe2 (2-TiMe2) and six other methyl titanium complexes bearing substituted indenyl ligands, has been investigated with different cocatalysts and at different polymerization temperatures and propylene concentrations. All complexes produce amorphous polypropylene (am-PP). The catalytic activity and molecular weight strongly depend on the substitution of the Cp ring: 2-TiMe2 gives polymers of lower molecular weight, while the presence of a methyl group in position 2 (as in 3-TiMe2) determines up to 4-fold increase in molecular weight. The type of cocatalyst influences mainly the catalytic activity, the borates being better activators than MAO, but also molecular weight, with again the borates giving higher molecular weights than MAO. 5-TiMe2-Ph3CB(C6F5)(4) shows an overall activation energy of polymerization of 7.35 kcal mol(-1). The rate of chain release is first order in monomer. The following activation energies for overall chain release have been calculated: DeltaDeltaE(double dagger) 2-TiMe2 = 3.4 kcal mol(-1), DeltaDeltaE(double dagger) 5-TiMe2 = 3.8 kcal mol(-1), AAET 3-TiMe2 = 6.3 kcal mol(-1). Even if all the polymers produced are amorphous, 2-TiMe2 and 5-TiMe2 show a microstructure unbalanced towards isotacticity, while 3-TiMe2, 6-TiMe2 and 8-TiMe2 are syndiotactic-enriched. Chiral induction comes mainly from a weak enantiomorphic site control. (C) 2002 Elsevier Science B.V. All rights reserved.
