Application

Hexyl isocyanate may be employed for the synthesis of following:
  • rigid-rod, helical isocyanate-based macromonomers[1]
  • rod-coil-rod triblock copolymers with 2-vinylpyridine, by living anionic polymerization[2]
  • chiral poly(n-hexyl isocyanate) (PHIC) macromonomers, by living anionic polymerization[3]

General description

Hexyl isocyanate has been investigated for its antigenicity in the guinea pig animal model of hapten-specific respiratory hypersensitivity.[4] Polymerization of n-hexyl isocyanate using rare earth tris(2,6-di-tert-butyl-4-methylphenolate) [Ln(OAr)3] as initiator has been studied.[5]
