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 hydrocarbon compound (HC), and subsequently precipitating said liquid clathrate (LC) obtaining said solid catalyst system (SC).
Claims16
A process for the preparation of a solid catalyst system (CS) comprising the steps of
- (I) preparing a liquid clathrate (LC) comprising
- (i) a lattice (L) being the reaction product of
- (α) aluminoxane (A),
- (β) 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
- (γ) a compound (B) being effective to form with the aluminoxane (A) and the organometallic compound (O) the lattice (L),
- and
- (ii) a guest (G) being an hydrocarbon compound (HC), and subsequently followed by
- (II) precipitating said liquid clathrate (LC) to obtain said solid catalyst system (SC),
- wherein said process does not comprise a step in which the liquid clathrate (LC) is emulsified.
