Abstract
As modifications of the effective catalyst precursor [dimethylsilanedi ylbis(benz[e]indenyl)]zirconium dichloride, the ansa-zirconocene compl exes Me2Si(cyclopenta[c]phenanthryl)(2)ZrCl2, Me2Si(cyclopenta[l]phena nthryl)(2)ZrCl2, Me2Si(2-methylcyclopenta[l]phenanthryl)(2)ZrCl2, and Me2Si(2-methyltetrahydrobenz[e]indenyl)2 have been synthesized. When a ctivated by methylaluminoxane (MAO), these complexes give highly activ e catalysts for the polymerization of propene to polymers with high is otacticities and molecular weights.
