Claims
- 1. A catalyst component which comprises the combination of an aluminoxane combined with a transitional metal compound, wherein the aluminoxane is of the formula II ##STR13## for the linear type and/or of the formula III ##STR14## for the cyclic type, in which, in the formulae II and III, R.sup.9 denotes a C.sub.1 -C.sub.6 -alkyl group or phenyl or benzyl and n is an integer from 2 to 50 wherein the transitional metal compound is (Methyl (phenyl)methylene) (9-fluorenyl) (cyclopentadienyl)zirconium dichloride or (diphenylmethylene) (9-fluorenyl) (cyclopentadienyl)zirconium dichloride.
- 2. The catalyst as claimed in claim 1, wherein said aluminoxane is methylaluminoxane.
- 3. The catalyst as claimed in claim 1, wherein the transitional metal compound is (Methyl(phenyl)methylene)(9-fluorenyl)(cyclopentadienyl)zirconium dichloride and said aluminoxane is methylaluminoxane.
- 4. The catalyst as claimed in claim 1, wherein the transitional metal compound is (diphenylmethylene)(9-fluorenyl)(cyclopentadienyl)zirconium dichloride and said aluminoxane is methylaluminoxane.
- 5. A catalyst component which comprises the combination of an aluminoxane combined with a transitional metal compound, wherein the aluminoxane is of the formula II ##STR15## for the linear type and/or of the formula III ##STR16## for the cyclic type, in which, in the formulae II and III, R.sup.9 denotes a C.sub.1 -C.sub.6 -alkyl group or phenyl or benzyl and n is an integer from 2 to 50 wherein said transitional metal compound is (arylalkylidene) 9-fluorenyl) (cyclopentadienyl)zirconium dichloride in which the aryl represents an aryl group having 6-10 carbon atoms.
- 6. A catalyst component which comprises the combination of an aluminoxane combined with a transitional metal compound, wherein the aluminoxane is of the formula II ##STR17## for the linear type and/or of the formula III ##STR18## for the cyclic type, in which, in the formulae II and III, R.sup.9 denotes a C.sub.1 -C.sub.6 -alkyl group or phenyl or benzyl and n is an integer from 2 to 50 wherein said transitional metal compound is (diarylmethylene) (9-fluorenyl)zirconium dichloride in which the aryl represents an aryl group having 6-10 carbon atoms.
