Titanium trichloride catalytic component and method for homo- or co-polymerization of alpha -olefin

摘要

A highly active titanium trichloride catalytic component to be used for polymerization of alpha -olefin has highly uniform particle size the mean value of which is adjustable to a desired value between 10 and 500 mu ; and a method for manufacturing an alpha -olefin polymer having extremely uniform particle diameter by using a catalyst which is prepared by combining the above stated catalytic component with an organo-aluminum compound. In the manufacture of the olefin polymer, deashing processes can be either omitted or simplified. Further, the pelletizing process on the catalytic component or the polymer also can be omitted.
