摘要

Abstract

An alternative cationic polymerization method is developed to produce high molecular weight polyisobutylene (HM-PIB) with molecular weights above 5 × 10

g/mol. The method involves micelle formation

via

functionalized low molecular weight polyisobutylene (LM-PIB) in non-polar solvent. One end of LM-PIB is modified with an imidazolium-containing ionic group

which together with the anion (

e.g

. Al

) works as Lewis acid. While the monomer isobutylene dissolves readily in non-polar solvent

polymerization can occur only within the micelle

which affords stable HM-PIB particles. HM-PIB with a molecular weight (MW) close to 1 × 10

g/mol was produced successfully with the described method.
