Free-flowing catalyst system for olefin polymerisation

摘要

A catalyst system containing metallocene(s), cocatalyst(s) and inert support(s). Also claimed are: (i) a process for the production of a free-flowing catalyst system, by making a metallocene/cocatalyst mixture in a suitable solvent or suspension medium, adding the mixture to a porous, preferably dehydrated inorganic support, removing solvent and isolating the supported catalyst; (ii) a free-flowing supported catalyst system obtained by this process; (iii) homo- or co-polymers obtained with this catalyst system; (iv) a process for the production of such (co)polymers from olefins using this catalyst system.
