PROCESS FOR POLYMERIZING OLEFINS

摘要

The present invention relates to a process for polymerizing olefins. In the process of the present invention, olefins are polymerized using a catalyst composed of a compound of a transition metal (e.g. zirconium) of Group IVB of the periodic table, an aluminoxane produced from trimethylaluminum, and an aluminoxane wherein at least one hydrocarbon group other than n alkyl groups is bonded to an aluminum atom. The present process can polymerize olefins with excellent polymerization activity and can produce an olefin polymer having a relatively large molecular weight even when the use amount of the aluminoxane produced from trimethylaluminum (which is expensive) is small.
