Preparation of a solid catalyst system

摘要

Liquid clathrate (LC) comprising
(a) a lattice (L) being the reaction product of
(i) aluminoxane (A),
(ii) an organometallic compound (C) of a transition metal (M) is a compound of formula (II)
€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ€ƒ (Cp) 2 RMX 2 €ƒ€ƒ€ƒ€ƒ€ƒ(II)
wherein
"M" is zirconium (Zr) or hafnium (Hf)
each "X" is independently a Ã-ligand,
each "Cp" is independently an indenyl ligand which coordinates to the transition metal (M), said indenyl ligand is substituted at least at the five membered ring and at the six membered ring of the indenyl ligand,
"R" is a bridging group linking said organic ligands (L),
(iii) an organo-silicon compound (OS) being effective to form the lattice (L) with the aluminoxane (A) and the organometallic compound (C),
and
(b) a guest (G) being an hydrocarbon compound (HC).
