The present invention relates to diimino compounds defined by following formulae: wherein n is 0 or 1; m is 1, 2 or 3; each R , equal to or different from each other, is selected from the group consisting of: hydrogen, a monovalent aliphatic or aromatic hydrocarbon group, optionally containing heteroatoms of group 14 to 16 of the periodic table of the elements and/or boron; with the proviso that al least one R group is represented by the formula R OSi(R)3; wherein each R is independently selected from the group consisting of: C1-C20 alkyl, C3-C20 cycloalkyl, C6-C20 aryl, C2-C20 alkenyl, C7-C20 arylalkyl, C7-C20 alkylaryl, C8-C20 arylalkenyl, C8-C20 alkenylaryl, linear or branched; preferably it is methyl, ethyl or propyl; each R , equal to or different from each other, is a divalent aliphatic or aromatic hydrocarbon group containing from 1 to 20 carbon atoms, optionally containing from 1 to 5 heteroatoms of groups 14, 15 or 16 of the periodic table of the elements and/or boron; each R , equal to or different from each other, is a radical which contains from 1 to 20 carbon atoms; this group optionally contains heteroatoms of group 14 to 16 of the periodic table of the elements and/or boron; R is a divalent aliphatic or aromatic hydrocarbon group containing from 1 to 20 carbon atoms, optionally containing from 1 to 5 heteroatoms of groups 14, 15 and 16 of the periodic table of the elements and/or boron; R , equal to or different from each other, is hydrogen or a radical which contains from 1 to 20 carbon atoms; this group optionally contains heteroatoms of group 14 to 16 of the periodic table of the elements and/or boron; This invention also relates to a process to prepare compounds represented by formula I or II above. Likewise this invention relates to a catalyst component comprising the product of the combination of the diimino ligand and a porous inorganic support. Further this invention also relates to the use of the catalyst component in combination with a cocatalyst to polymerize olefins.
