Abstract:
What is described is a process for preparing functionalized polyisobutenes, in which isobutene or an isobutene-containing monomer mixture is polymerized in the presence of a Lewis acid and of an initiator, and the polymerization is terminated with a mixture of a phenol and a Lewis acid and/or a Brønsted acid. The terminal phenol groups can be derivatized or reduced to cyclohexanol systems.
