Claims
- 1. A catalyst for the polymerization of .gamma.-olefins containing from 2 to 30 carbon atoms, to form non-crystalline, hydrocarbon-soluble polymers; comprising,
- (a) titanium trichloride of the general formula TiCl.sub.3.mAlCl.sub.3 wherein m is from 0.00 to 1.00, which is selected from the group consisting of products produced by;
- (1) reducing titanium tetrachloride with aluminum,
- (2) reducing titanium tetrachloride with hydrogen,
- (3) reducing titanium tetrachloride with an organometallic compound, or
- (4) milling titanium tetrachloride with a Group II metal, in conjunction with
- (b) a ketone,
- (c) a compound selected from the group consisting of Group IA or IIA metal halides, transition metals, quaternary ammonium halide or sulfate salts, alkaline earth phosphates and alkyl alkali metal sulfates,
- (d) an organo-aluminum halide of the formula AlR.sub.n X.sub.3- n where R is a hydrocarbon radical, X is halogen and n is 2 or 3, and
- (e) a catalyst modifier of the formula PR.sub.1 R.sub.2 R.sub.3 or P(OR.sub.1) (OR.sub.2) (OR.sub.3) wherein R.sub.1, R.sub.2, and R.sub.3 are, independently, aryl, alkyl, aralkyl, or alkaryl.
- 2. A catalyst as described in claim 1 wherein the ketone is saturated monocyclic monoterpenic ketone or a bicyclic monoterpenic.
- 3. A catalyst as described in claim 2 wherein the TiCl.sub.3 contains 0.33AlCl.sub.3, the bicyclic monoterpenic ketone is camphor, the ionic compound is sodium bromide, the organo aluminum halide is diethyl aluminum chloride and the catalyst modifier is triphenylphosphine.
