The present invention is related to diimino compounds of formulae (I) R2-N=C(R1)(R3)nC(R1)=N-R2 and (II) (R1)2C=N-(CR24)m-N=C(R1)2 functionalized with at least one siloxy group. Said diimino compounds are useful for obtaining a solid catalyst component for polymerizing olefins wherein the diimino compound of formulae (I) or (II) is bonded to a porous inorganic support and to a transition metal selected from groups 8, 9 and 10 of the periodic table. This invention also relates to a process for preparing said diimino compounds of formulae (I) or (II), to a process for obtaining said solid catalyst component comprising the combination of the diimino compound and a porous inorganic support. Further, the invention also relates to the use of said solid catalyst in combination with a cocatalyst to polirnenrze olefins.
