Oligomers and polymers of aminoalkenes

A process for preparing oligomers and polymers which comprises oligomerizing or polymerizing components A) and B)

• A) from 1 to 30 mol % of at least one aminoalkene of the formula I ##STR12## where X is an integer from 0 to 25 and
• R.sup.1 to R.sup.4 are hydrogen, C.sub.1 - to C.sub.10 -alkyl, 5- to 7-membered cycloalkyl which, in turn, can carry C.sub.1 - to C.sub.6 -alkyl groups as substituents or C.sub.6 - to C.sub.15 -aryl
• and
• B) from 70 to 99 mol % of at least one alkene having from 2-10 carbon atoms,
• for x=1 in formula I propene being excluded as component B), at from 0.5 to 3000 bar and from -50.degree. to +300.degree. C. in the presence of a catalyst system which as active components contains metallocene complexes of the formula II ##STR13## where the substituents have the following meanings:
• M is titanium, zirconium, hafnium, vanadium, niobium or tantalum,
• X is fluorine, chlorine, bromine, iodine, hydrogen, C.sub.1 - to C.sub.10 -alkyl, C.sub.6 - to C.sub.15 -aryl or --OR.sup.12,
• R.sup.12 being C.sub.1 - to C.sub.10 -alkyl, C.sub.6 - to C.sub.15 -aryl, alkylaryl, arylalkyl, fluoroalkyl or fluoroaryl each having 1 to 10 C atoms in the alkyl radical and 6 to 20 C atoms in the aryl radical,
• R.sup.7 to R.sup.11 are hydrogen, C.sub.1 - to C.sub.10 -alkyl, 5- to 7-membered cycloalkyl which, in turn, can carry a C.sub.1 - to C.sub.10 -alkyl as a substituent, C.sub.6 - to C.sub.15 -aryl or arylalkyl, it also being possible, if desired, for two adjacent radicals together also to be a cyclic group containing 4 to 15 C atoms, or Si(R.sup.13).sub.3 where
• R.sup.13 is C.sub.1 - to C.sub.10 -alkyl, C.sub.6 - to C.sub.15 -aryl or C.sub.3 - to C.sub.10 -cycloalkyl,
• Z is X or ##STR14## the radicals R.sup.14 to R.sup.18 being hydrogen, C.sub.1 - to C.sub.10 -alkyl, 5- to 7-membered cycloalkyl which, in turn, can carry a C.sub.1 - to C.sub.10 - alkyl as a substituent, C.sub.6 - to C.sub.15 -aryl or arylalkyl and it being possible, if desired, for two adjacent radicals together also to be a cyclic group containing 4 to 15 C atoms, or Si(R.sup.19).sub.3 where
• R.sup.19 is C.sub.1 - to C.sub.10 -alkyl, C.sub.6 - to C.sub.15 -aryl or C.sub.3 - to C.sub.10 -cycloalkyl,
• or the radicals
• R.sup.10 and Z together being a group --(Y(R.sup.20).sub.2).sub.n --E--, where
• Y is silicon, germanium, tin or carbon,
• R.sup.20 is hydrogen, C.sub.1 - to C.sub.10 -alkyl, C.sub.3 -C.sub.10 -cycloalkyl or C.sub.6 - to C.sub.15 -aryl
• n is a number 1, 2, 3 or 4
• E is ##STR15## where R.sup.21 is C.sub.1 - to C.sub.10 -alkyl, C.sub.6 - to C.sub.15 -aryl, C.sub.3 - to C.sub.10 -cycloalkyl, alkylaryl or Si(R.sup.22).sub.3
• where R.sup.22 is C.sub.1 - C.sub.10 -alkyl, C.sub.6 - to c.sub.15 -aryl, C.sub.3 - to C.sub.10 -cycloalkyl or alkylaryl
• and
• D) a metallocene ion-forming compound,
• and, optionally open-chain or cyclic alumoxane compounds of the formula III or IV ##STR16## R.sup.23 being a C.sub.1 - to C.sub.4 -alkyl group and m being an integer from 5 to 30.
