Zusammenfassung:	SUPPORTED IONIC METALLOCENE CATALYST MAY BE PREPARED BY A PROCESS COMPRISING THE FOLLOWING STEPS: (I) MIXING TOGETHER IN A SUITABLE SOLVENT A) A 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.THE METALLOCENE COMPLEX IS TYPICALLY AN ETHYLENE BIS INDENYL ZIRCONIUM (II) COMPLEX AND THE RESULTANT CATALYSTS ARE PARTICULARLY SUITABLE FOR USE IN THE GAS PHASE WHERE CONTROL OF MELT INDEX AND A WIDE RANGE OF MOLECULAR WEIGHTS DISTRIBUTIONS MAY BE ACCESSIBLE.IMPROVED OPTICALS MAY ALSO BE ACHIEVABLE.
