Beschreibung
Zusammenfassung:	The invention relates to a method for preparing a carrier of an olefin polymerization catalyst. The carrier is a terpolymer polymerized by divinyl benzene, styrene and hydroxyethyl methylacrylate. The carrier is prepared by a dispersion polymerization method, the reaction monomers divinyl benzene, styrene and hydroxyethyl methylacrylate are sequentially added into a dispersion liquid, the particle shape of the terpolymer carrier is controlled by adding a stabilizing agent, and the pore diameter of the terpolymer carrier is adjusted by adding a pore-foaming agent. The terpolymer carrier prepared by the method is monodisperse porous microsphere, the particle size and pore diameter of the carrier are controllable, loading of a metallocene catalyst system is facilitated, and the formed catalyst has a relatively high activity.
