Abstract
Abstract The novel metallocenes of the formula I ##STR1## in which, preferably, M 1 is Zr or Hf, R 1 and R 2 are alkyl or halogen, R 3 and R 4 are hydrogen, R 5 and R 6 are alkyl or haloalkyl, --(CR 8 R 9 ) m --R 7 --(CR 8 R 9 ) n -- is a single- or multi-membered chain in which R 7 may also be a (substituted) hetero atom, and m+n is zero or 1, form, together with aluminoxanes as cocatalysts, a very effective catalyst system for the preparation of polyolefins of high molecular weight.
