    Abstract: Preparation of highly reactive isobutene homo- or copolymers having M n =from 500 to 45 000 by polymerizing isobutene in the liquid phase in the presence of a dissolved, dispersed or supported boron-containing catalyst complex, by using, as the catalyst complex, a protic acid compound I [H + ] m+1 [R 1 R 2 R 3 B-(-A m+ -BR 5 R 6 -) n -R 4 ] (m+1)- .L x (I) R 1 to R 6 each independently aliphatic, heterocyclic or aromatic, fluorinated hydrocarbon radicals having in each case from 1 to 18 carbon atoms, or silyl groups comprising C 1 to C 18 hydrocarbon radicals, A nitrogen-containing bridging member which forms covalent bonds to the boron atoms via its nitrogen atoms, L neutral solvent molecules, n=0 or 1, m=0 or 1 and x is >=0.

    Abstract: Process for producing a supported catalyst which comprises at least 75% by weight of Al 2 O 3 , whose proportion of Al 2 O 3 in the delta or theta modification is, based on the proportion of Al 2 O 3 , at least 1% and which comprises a rhenium compound and, if appropriate, a promoter as active component (A), which comprises a) converting a customary support (S) which comprises at least 75% by weight of Al 2 O 3 and to which a promoter may, if appropriate, have been applied is converted into a modified support (S) whose proportion of Al 2 O 3 in the delta or theta modification is, based on the proportion of Al 2 O 3 , at least 1% by calcining the customary support (S) at a temperature of from 750 to 1100°C., b) producing a supported catalyst precursor from the modified support (S) by applying the active component (A) comprising the rhenium compound to the modified support (S) and c) calcining the supported catalyst precursor at a temperature of from 500 to 750° C.
