Process for polymerizing olefins.

摘要

A catalyst comprising a metallocene compound in the IVB group and an alumoxane compound is improved to alter an alumoxane compound with an inexpensive organoaluminum compound while polymerization activity is maintained at a high level, wherein a process for polymerizing an olefin with a catalyst comprising a metallocene compound in the IVB group and an organoaluminum compound and a magnesium halide having reducing ability and solubilized is disclosed. Polyolefins are obtainable in a low price and a high yield with the use of a conventional organoaluminum compound.
