Abstract

Metal alkyl-arene, (η6-arene)2AlqXrRs (I) M (η6-arene)AlqXrRs (Ia) wherein: M = Zr, Hf, or mixts. thereof, preferably zirconium; arene represents a benzene, or a benzene 10 substituted with from 1 to 6 linear or branched C1-C6 alkyl groups, or mixts. thereof; X represents a halogen atom selected from chlorine, bromine, fluorine, iodine, preferably chlorine; R represents a linear or branched C1-C15 alkyl group; q is a no. ranging from 2 to 6, preferably 3 for a metal alkyl-arene I, 2 for a metal alkyl-arene Ia; r is a no. ranging from 1 to 20, preferably 9 for a metal alkyl-arene Ia, 6 for a metal alkyl-arene Ia; s is a no. ranging from 1 to 6, preferably 2. Said metal alkyl-arene can be advantageously used for the prepn. of solid components of catalysts for the (co)polymn. of α-olefins
