Abstract
PURPOSE: To prepare a polyolefin having a wide molecular weight distribution with a good catalytic efficiency, by polymerizing an olefin using a catalyst consisting of (A) a solid component obtained by simultaneous pulverization of the reaction product between MgO and AlCl3 under heating with a Ti or V compound and (B) an organometallic compound.
