Isobutenyl-telechelic polyisobutylenes (PIBs) were synthesized by reacting tert-chlorine-telechelic and living PIBs with isobutenyltrimethylsilane (IBTMS) in the presence of TIC14 in CH2Cl2/hexane (40/60 v/v) solvent mixtures at -78Β°C. In order to obtain PIB oligomers, living polymerization of isobu
