Method for producing highly reactive isobutylene homo- or copolymers using metal-containing catalyst complexes

Method for producing highly reactive isobutylene homo- or copolymers using metal-containing catalyst complexes

The invention relates to the production of highly reactive isobutylene homo- or copolymers with Mn = 500 to 45,000 by polymerizing isobutylene in liquid phase in the presence of a dissolved, dispersed or supported boron-containing catalyst complex by using, as a catalyst complex, a Bronsted compound...

Zusammenfassung:The invention relates to the production of highly reactive isobutylene homo- or copolymers with Mn = 500 to 45,000 by polymerizing isobutylene in liquid phase in the presence of a dissolved, dispersed or supported boron-containing catalyst complex by using, as a catalyst complex, a Bronsted compound (I) [H]m+1 [R R R B-(-A-BR R -)n-R ] Lx (I), in which: R to R represent aliphatic, heterocyclic or aromatic fluorine-containing hydrocarbon radicals, which are independent of one another and which each have 1 to 18 carbon atoms or silyl groups containing C1 to C18 hydrocarbon radicals; A represents a bridge member that, via its nitrogen atoms forms bonds which are covalent to the boron atoms; L represents neutral solvent molecules; n = 0 or 1; m = 0 or 1, and; x = 0.
