Ewen John A, Elder Michael J: Preparation of metallocene catalysts for polymerization of olefins.. Fina Technology, May 8, 1991: EP0426637-A2 (222 worldwide citation)

This invention uses a new method of producing ionic metallocene compounds. These compounds are useful as catalysts for polymerization of olefins, primarily propylene. This method uses an ionizing agent which ionizes the neutral metallocene compound. The ionizing ionic compound does not contain an ac ...
