Process for producing alpha-olefin polymers.

摘要

A process for producing an alpha -olefin polymer characterized in that an alpha -olefin is brought into contact with a catalyst which comprises the following components (A) and (B) and has undergone the preliminary polymerization of an alpha -olefin under the following preliminary polymerization conditions (i) and (ii) thereby polymerizing the alpha -olefin: preliminary polymerization conditions: (i) the polymer produced by the preliminary polymerization has a number average molecular weight based on the measurement of GPC of at least 100,000; (ii) the amount of the polymer produced by the pre-polymerization exceeds 50 g of the polymer/g of the component (A); component (A): a prescribed transition metal compound having a cyclopentadienyl ligand, component (B): a prescribed alumoxane. A polymer having a particle diameter of 100 mu m or more can be stably produced by a simple and easy method, and the polymer can be handled easily.
