New contributions of this work are as follows:(1). Preparation of Spherical MgCl_2-Supported Late-Transition Metal Catalysts for Ethylene Polymerization Facile and effective immobilization of late-transition metal catalysts. 2,3-bis-(2,6-diisopropylphenyl) butane diimine nickel dibromide (1) and 2,6-bis-[1-(2,4,6-trimethylphenylimino)ethyl]pyridine iron dichloride (2), for ethylene polymerization has been achieved, using spherical MgCl_2 supports obtained by thermal dealcoholization of MgCl_2·2.56C_2H_5OH, and the effects of dealcoholization temperature on supported late-transition metal catalysts and the properties of resultant polymers were studied, the results indicated that: 1.Supports with appropriate mechanical strength, high surface area and high porosity could be prepared by thermal dealcoholization of spherical MgCl_2·2.56C_2H_5OH supports; 2.BET, XRD, IR, SEM, GPC and DSC analyses indicate that the activities of the supported late-transition metal catalysts and the properties of resultant polymers are strongly dependent on the dealcoholization temperature.
