Complexes (R 1 Cp)(R 2 Ind)ZrCl 2 , the catalysts previously reported active for ethylene polymerization showed high activity in ethylene/1‐hexene copolymerization and propylene polymerization in the presence of MAO. The content of 1‐hexene in copolymers ranged from 1.2% to 3.2%. In propylene polymerization the complex 1 showed the highest activity, up to 1.2×10 6 g of polypropylene per mol of catalyst per hour. Based on the analysis of NMR spectral data, the relationships between complex structures and polymerization results were explored.
