Abstract: Preparation of highly reactive isobutene homo- or copolymers having Mn=from 500 to 1 000 000 by polymerizing isobutene in the liquid phase in the presence of a dissolved, dispersed or supported metal-containing catalyst complex by using, as the catalyst complex, a compound I Zn+[MXa(OR)b]n-.Lx (I) M metal atom from the group of boron, aluminum, gallium, indium and thallium, R each independently aliphatic, heterocyclic or aromatic hydrocarbon radicals which have in each case from 1 to 18 carbon atoms and may comprise fluorine atoms, or silyl groups comprising C1 to C18 hydrocarbon radicals, X halogen atoms, Z proton (n=1), optionally substituted ammonium (n=1) or n-valent metal cation, L neutral solvent molecules, a integer from 0 to 3, b integer from 1 to 4, where a+b=4, and x>=0.
