| 摘要 |
The invention relates to the production of highly reactive isobutylene homo-or copolymers with Mn = 500 to 1,000,000 by polymerizing isobutylene from technical flows of C4-hydrocarbon having a isobutylene content ranging from 1 to 90 % by weight in liquid phase in the presence of a dissolved, dispersed or supported catalyst complex by using, as a catalyst complex, a Bronsted acid compound (I) [H+]k Yk- Lx (I) Yk- weakly coordinating k-valent anion, which contains at least one carbon-containing grouping; L represents neutral solvent molecules, and; x = 0.
