Claims
- 1. A composition of matter comprising the reaction product of polymethylaluminoxane and a complex corresponding to the formula: CpTiX.sub.3, wherein Cp is a .pi.-bonded cfyclopentadienyl group, a ring fused derivative thereof or a substituted derivative f the foregoing wherein the substituents are selected from the group consisting of alkyl, aryl and silyl substituents containing up to 18 carbons, and X is independently each occurrence halide, OR, or NR.sub.2, wherein R is independently each occurrence an aliphatic, cycloaliphatic or aromatic hydrocarbon group having from 1 to about 12 carbon atoms and provided further that in at least one occurrence X is OR or NR.sub.2.
- 2. A composition according to claim 1, wherein the atomic ratio of Al:Ti therein is from about 50:1 to about 10,000:1.
- 3. A composition according to claim 2, wherein the atomic ratio of Al:Ti therein is from about 100:1 to about 1,000:1.
- 4. A composition according to claim 1, wherein X is OR in each occurrence and R is selected from the group consisting of phenyl and C.sub.1-6 alkyl.
- 5. A composition according to claim 1 wherein Cp is pentamethylcyclopentadiene.
- 6. A composition according to claim 1 wherein X is made in each occurrence.
- 7. A composition according to claim 4 wherein X is phenoxy in each occurrence.
