High efficiency catalyst for polymerizing olefins

Claim 1

A catalytic reaction product of (A) a complex of a trivalent titanium halide with water or an organic electron donor selected from alcohols having 2-8 carbon atoms, ethers having 2 to 20 carbon atoms, ketones having 3-20 carbon atoms, amines having 1-20 carbon atoms, olefins having 2-20 carbon atoms and mixtures thereof, (B) an organomagnesium component selected from (1) an organomagnesium compound or (2) a complex of an organomagnesium compound and an organometallic compound in an amount sufficient to solubilize the organomagnesium compound in hydrocarbon, said organomagnesium compound and said complex being represented respectively by the following formulas MgR.sub.2 and MgR.sub.2 × MR.sub.y wherein each R 2 is independently a hydrocarbyl group having from 1 to 8 carbon atoms, M is a metal selected from Al, Zn, Si, Sn and P, y is the number of hydrocarbyl groups and corresponds to the valencey of M and x is about 0.001 to 10 and (C) a halide source selected from (1) an active non-metallic halide, said non-metallic halide corresponding to the formula R'X wherein R' is hydrogen or an organic group at least as active as sec-butyl and does not poison the catalyst and X is halogen or (2) a metallic halide corresponding to the formula MR y-a X a wherein M is a metal of Group 3a or 4a of Mendeleev's Periodic Table of Elements, R is a monovalent organic radical, X is halogen, y is a number corresponding to the valence of M and a is a number from 1 to y; provided that the proportions of the foregoing components of said catalytic reaction product being such that the atomic ratio of Mg:Ti is within the range which is from about 1:1 to about 2000:1, either B, C or a mixture thereof contains aluminum or an aluminum trialkyl or an aluminum alkyl halide is added separately such that the atomic ratio of Al:Ti is within the range from about 0.1:1 to about 2000:1, the atomic ratio of Mg:X is within the range from about 0.01:1 to about 1:1.
