Abstract
Process for the preparation of a solid catalyst system (CS) comprising the steps of preparing a liquid clathrate (LC) comprising (a) a lattice (L) being the reaction product of (i) aluminoxane (A), (ii) an organometallic compound (O) of a transition metal (M) of Group 3 to 10 of the Periodic Table (IUPAC 2007) or of an actinide or lanthanide, and (i) a compound (B) being effective to form with the aluminoxane (A) and the organometallic compound (O) the lattice (L), and (b) a guest (G) being an hydro-carbon compound (HC), and subsequently precipitating said liquid clathrate (LC) obtaining said solid catalyst system (SC).
