The immobilization of the soluble precatalysts [(ArN C(Me)) 2 C 5 H 3 N]FeCl 2 , where Ar = 2,4,6-trimethylphenyl (A) or 2,6diisopropylphenyl (B), on supports derived from a spherical MgCl 2 -alcohol adduct yields active supported systems for ethylene polymerization. The activity of the supported ca
