Polyolefins and their functionalized derivatives

Polymers of C.sub.2 -C.sub.12 -alkenes are prepared at from -50 to 300.degree. C. and from 0.5 to 3000 bar in the presence of a catalyst system by a process in which a compound of the general formula I ##STR1## where M.sup.1 is boron, aluminum, gallium, indium or thallium and
