ABSTRACT:
Alpha-olefins are polymerized in the presence of a catalyst which comprises (A) a zirconium carboxylate, a chromium carboxylate or mixture thereof; (B) a solid catalyst support; (C) an organometallic activating agent or cocatalyst and (D) a trivalent or tetravelent titanium compound. The resultant polymers have a high molecular weight and a narrow molecular weight distribution.
