Process for polymerizing olefins.

摘要

Process for polymerizing olefins using a catalyst composed of a transition metal catalyst component, an aluminoxane component and an organoaluminium component. In the process of this invention, the catalyst exhibits excellent polymerization activity with the use of a small amount of the aluminoxane. The polymerization process gives olefin polymers having a narrow molecular weight distribution and by the copolymerization of two or more olefins, gives olefin copolymers having a narrow molecular weight distribution and a narrow composition distribution.
