摘要: A method for preparing a propylene (co)polymer having a substantially high syndiotactic structure and a desired molecular weight which comprises the step of (co)polymerizing propylene or propylene and a small amount of another olefin by the use of a transition metal compound catalyst having asymmetric ligands in the presence of a specific internal olefin.
