Abstract

1-Octadecene (C18) was polymerized by using different metallocene catalysts. The rac-Et(Ind)2ZrCl2/MAO (I) and rac-Me2Si(Ind)2ZrCl2/MAO (III) presented the highest activity as compared with rac-Et(2-Me-Ind)2ZrCl2/MAO (II) and Ph2C(Flu)(Cp)ZrCl2/MAO (IV) catalysts. Catalyst IV produced polymers with highest molecular weights. The microstructure of the polymers was determined by 13C-NMR spectroscopy. Catalyst systems I, II and III produced isotactic polymers while catalyst IV produced polymers with mainly syndiotactic structures but with large amount of stereoregular error.
