摘要： PURPOSE:To prepare the subject highly strong and active catalyst comprising porous spherical particles by stirring the complex compound of a Mg compound with an alcohol in the presence of a surfactant in a solvent at a temperature of >= the melting point, rapidly cooling the stirred suspension, drying the resultant solid particles and subsequently treating the dried solid particles with a halogenated Ti and an electron-donor. CONSTITUTION:A magnesium compound (e.g. magnesium chloride) and an alcohol (e.g. ethanol) are reacted with each other in an inactive organic solvent (e.g. hexane) to prepare a complex compound, which is heated and stirred in the presence of a nonionic surfactant at a temperature range of >= the melting point to give a suspension solution. The suspension solution is rapidly cooled to form a spherical solid component without the evaporation of the alcohol. The solid component is partially dried and subsequently treated with titanium halide (e.g. titanium tetrachloride) and an electron donor (e.g. isobutyl phthalate) to provide the objective polymerization catalyst component.
