Copolymerization of Ethylene/1‐hexene and Polymerization of Propylene with Cp‐indenyl Zirconium Complexes
View through CrossRef
AbstractComplexes (R1Cp)(R2Ind)ZrCl2, 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 1.2×106 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.
