The synthesis and characterization of metallocene complexes Cp₂^tMCl₂[Cp^t=^tBuC₅H₄,M=Ti(Ⅰ), Zr(Ⅱ), Hf(Ⅲ)] are presented in catalyzation polymerization of butene-1. The metallocene catalysts and polybutenes have been characterized by IR, ¹H NMR and EI-MS spectra and DSC measurements. The catalytic features for butene-1 polymerization were studied under different conditions. The results showed that Cp₂^tMCl₂/MAO had high activity for butene-1 polymerization, improving the tacticity and molecular weight of the polymers obtained.
