ABSTRACT:
A new catalyst useful in the polymerization of olefins, especially propylene, is disclosed. The catalyst is produced by contacting at least one hydrocarbon soluble magnesium compound with a modifying compound selected from the group consisting of silicon halides, boron halides, aluminum halides, alkyl silicon halides and mixtures thereof. The product of this contact is contacted with a first titanium-containing compound having the structural formula Ti(OR).sub.n X.sub.m, where R is hydrocarbyl; X is halogen; n is an integer of 1 to 4; and m is 0 or an integer of 1 to 3, with the proviso that the sum of n and m is 4, and a second titanium-containing compound having the structural formula Tix.sup.1.sub.p (OR.sup.1).sub.q where X.sup.1 is halogen; R.sup.1 is hydrocarbyl; p is an integer of 1 to 4; and q is 0 or an integer of 1 to 3, with the provisos that the sum of p and q is 4 and that the first and second titanium-containing compounds are not identical.
