Abstract
PURPOSE: To obtain a high polymer having an improved particle size distribution and stereoregularity, by polymerizing ethylene or α-olefins by the use of a Ziegler type catalyst prepared by simultaneous pulverization of a starting titanium component with a specific organolauminium compound, and by modifying the product thus obtained in contact with an inert organic solvent.
