Abstract
PURPOSE: To prepare an olefin polymer or copolymer having a broad molecular weight distribution and improved moldability without deashing, by carrying out the polymerization in the presence of a new catalyst comprising a highly active titanium component containing titanium, magnesium and a halogen, an organoaluminum compound component and a specific halogen compound component.
CONSTITUTION: Olefins (e.g. ethylene) are polymerized in the presence of a catalyst comorising (A) a highly active titanium component at least containing titanium, magnesium and a halogen (e.g. the combination of magnesium chloride and titanium tetrachloride), (B) an organoaluminum compound component (e.g. triethylaluminum) and (C) a halogen compound of a IWVIII group element in the periodic table (other than halogen compounds of magnesium, aluminum, titanium, vanadium and carbon) (e.g. silicon tetrachloride). The preferable atomic ratio [halogen in (C)]/[aluminum in (B)] is 2/1W1/100.
