Abstract
Supported inonic metallocene catalyst prepared by a process comprising the following steps;(i) mixing together in a suitable solvent(a) an metallocene complex,(b) an ionic compound comprising a cation and an anion having up to 100 non-hydrogen atoms and containing at least one substituent comprising a moiety having an active hydrogen, and(c) optionally a support material,(ii) treating the mixture obtained in (i) with an organometallic compound, and(iii) addition of a support material if not added in step (i), and(iv) removing the solvent.
