Claim:
1. A process for the preparation of a solid catalyst system (CS) comprising the steps of (i) preparing a liquid clathrate (LC) comprising a mixing of an aluminoxane (A), an aromatic compound (AC) and an organo-silicon compound (OS), wherein the mol-ratio between the organo-silicon compound (OS) and aluminum (Al) of the aluminoxane (A) [(OS)/(Al)] is equal or below 0.1, (ii) mixing said liquid clathrate (LC) with an organometallic compound (C), (iii) obtaining a liquid mixture (MI), wherein the liquid mixture (MI) is homogeneous, precipitating the solid catalyst system (CS) out of said liquid mixture (MI) by adding a saturated aliphatic compound to said liquid mixture (MI), and (iv) optionally recovering particles of the solid catalyst system (CS), wherein during the process no carrier material is added.
