摘要： A process is disclosed for preparing polyalk-1-enes by polymerising alk-1-enes with a bis(cyclopentadienyl)chromium-II compound (I), in which the cyclopentadienyl ring may bear inert organic rests, adsorbed on an inorganic oxidic substrate. The process is characterised in that polymerisation is carried out in the presence of an organometallic compound of a metal of the I to III main group or of a metal hydride, in particular n-butyllithium.
