End-quenching the living polymerization of isobutylene with acetyl sulfate |
摘要 |
A one-pot method of preparing sulfonic acid-terminated polyisobutylene by sulfonation with acetyl sulfate of living polyisobutylene in a single step. The method permits preparation of sulfonated telechelic polyisobutylenes (STPs) by "inifer" initiated carbocationic polymerization of isobutylene with Lewis acid to form a polymer, followed by the addition in the same reaction vessel of acetyl sulfate at the polymerization temperature or the decomposition temperature of the complex.
