Abstract: A process for preparing a solid support for a procatalyst suitable for preparing a catalyst composition for olefin polymerization, said process comprising: A. providing or preparing Compound R 4 z MgX 4 2‑z Wherein: r is R 4 Independently selected from linear, branched, or cyclic hydrocarbyl groups independently selected from alkyl, alkenyl, aryl, aralkyl, or alkylaryl groups, and one or more combinations thereof; x is X 4 Independently selected from fluoride, chloride, bromide or iodide; and 0 (0)<z<2; and B. allowing compound R to react 4 z MgX 4 2‑z With silane compounds Si (OR) 5 ) 4‑n (R 6 ) n Contact to produce Mg (OR) 1 ) x X 1 2‑x Wherein: r is R 1 、R 5 And R is 6 Each independently selected from linear, branched, or cyclic hydrocarbyl groups independently selected from alkyl, alkenyl, aryl, aralkyl, alkoxycarbonyl, or alkylaryl groups, and one or more combinations thereof; is (1) 1 Independently selected from fluoride, chloride, bromide or iodide; n is 0 to 4;0<z<2; and 0 (0)<x<2; wherein in step B an initiator compound is added to obtain a solid support, the initiator compound being selected from the group consisting of ketones, diketones, esters, diesters and benzamides.
