Claim 10

Dependent Claim 42 words

A catalyst for polymerizing an olefin which comprises a combination of (1) a solid component prepared by treating a mixture of (a) a titanium tetrahalide, (b) a vanadyl alcoholate and (c) a vanadyl trihalide, with an organoaluminum compound; and an organoaluminum compound.

Claim 11

Dependent Claim 42 words

A catalyst for polymerizing an olefin which comprises a combination of (1) a solid component prepared by treating a mixture of (a) a titanium tetrahalide, (b) a vanadyl alcoholate and (c) a vanadyl trihalide, with an organoaluminum compound; and an organoaluminum compound.

Claim 12

Dependent Claim 29 words

The catalyst of claim 9, wherein the molar ratio of the titanium tetrahalide to the vanadyl alcoholate and the vanadyl trihalide is in the range of 0.05 - 10.

Claim 13

Dependent Claim 21 words

The catalyst of claim 9, wherein the molar ratio of the vanadyl trihalide to the vanadyl alcoholate is less than 5.

Claim 14

Dependent Claim 32 words

The catalyst of claim 9, wherein said organoaluminum compound is present in said solid component (1) in an amount greater than an equimolar amount relative to the total titanium and vanadium compounds.

Claim 15

Dependent Claim 118 words

A process for polymerizing an olefin which comprises effecting said polymerization in contact with a catalyst of a combination of (1) a solid component prepared by treating a mixture of (a) titanium tetrachloride, (b) n-butoxy vanadyl and (c) vanadyl trichloride, with ethyl-aluminum sesquichloride; and (2) triethylaluminum, wherein the molar ratio of (a) to (b) + (c) is 0.50-10 and the molar ratio of (c) to (b) is less than 5 and wherein the components (a), (b) and (c) are mixed in benzene and then the ethyl-aluminum sesquichloride component is added and the mixture stirred and the resulting solid component is recovered; wherein all mixing operations are carried out in an argon atmosphere at a temperature of 0°-150° C.

Claim 16

Dependent Claim 118 words

A process for polymerizing an olefin which comprises effecting said polymerization in contact with a catalyst of a combination of (1) a solid component prepared by treating a mixture of (a) titanium tetrachloride, (b) n-butoxy vanadyl and (c) vanadyl trichloride, with ethyl-aluminum sesquichloride; and (2) triethylaluminum, wherein the molar ratio of (a) to (b) + (c) is 0.50-10 and the molar ratio of (c) to (b) is less than 5 and wherein the components (a), (b) and (c) are mixed in benzene and then the ethyl-aluminum sesquichloride component is added and the mixture stirred and the resulting solid component is recovered; wherein all mixing operations are carried out in an argon atmosphere at a temperature of 0°-150° C.
