ABSTRACT:
A catalyst component comprising a titanium trichloride material and a saturated monocyclic monoterpenic ketone or a bicyclic monoterpenic ketone. A catalyst employing the component and an organoaluminum compound is used to polymerize alpha olefins, and particularly propylene. The monoterpenic ketone is effective in increasing the stereoregularity of the polymer.
