This series of papers concern new materials for possible biological applications created by combining the chemistry of highly reactive cyanoacrylates (CAs) with polyisobutylene (PIB) rubbers. First, a new strategy for the synthesis of CA–telechelic PIBs is described. Subsequently, the strategy is employed for the synthesis of low viscosity (syringible) CA–telechelic three‐arm star PIB [Ø(PIB–CA) 3 ]. The intermediates of the synthesis route are characterized by 1 H NMR spectroscopy. Injecting liquid Ø(PIB–CA) 3 into living tissue (fresh chicken egg) produces a bolus of crosslinked PIB rubber. The spectacular oxidative resistance of this rubber is documented by its resistance to concentrated HNO 3 . A structural model of the crosslinked rubber obtained upon contacting Ø(PIB–CA) 3 with proteinaceous tissue is proposed. Copyright © 2007 John Wiley & Sons, Ltd.
