Beschreibung
Zusammenfassung:	The invention relates to a solid catalyst system comprising a chromium compound, a silicon oxide support and a compound represented by the general formula (R4)2-N-R3 (I), wherein R4 is represented by R1-Al-OR2 wherein R1 is selected from C1-C8 alkyl groups and OR2 is selected from C1-C8 alkoxyl groups and R3 is a C3-C8 linear, branched or cyclic alkyl group. L'invention concerne un système catalytique solide comprenant un composé de chrome, un support d'oxyde de silicium et un composé représenté par la formule générale ((R4)2-N-R3 (I), R4 étant représenté par R1-Al-OR2 dans laquelle R1 est sélectionné parmi des groupes alkyle en C1-C8 et OR2 est sélectionné parmi des groupes alcoxy en C1-C8 et R3 est un groupe en C3-C8 linéaire, ramifié ou cyclique.
