Process for the preparation of catalyst paste and products thereof

Abstract

A process for the preparation of a catalyst paste comprising the following steps: a) obtaining a slurry in an organic solvent containing at least: a1) a support bearing functional groups; a2) a trialkylaluminum of formula (Ra)3Al wherein Ra, equal to or different from each other is a C1-C20 hydrocarbon radical optional containing heteroatoms belonging to groups 13-17 of the periodic table of the elements; a3) a compound of formula (I) (R1)x-A-(OH)y  (I) wherein: A is an atom of group 13 or 15 of the Periodic Table; R1 equal to or different from each other, are C1-C40 hydrocarbon radicals optionally containing heteroatoms belonging to groups 13-17 of the periodic table of the elements; Y is 1 or 2; X is 1 or 2; provided that x+y=3; a4) a transition metal organometallic compound; b) washing the resulting slurry one or more times with oil.
