General description
Hexyl isocyanate has been investigated for its antigenicity in the guinea pig animal model of hapten-specific respiratory hypersensitivity. Polymerization of n-hexyl isocyanate using rare earth tris(2,6-di-tert-butyl-4-methylphenolate) [Ln(OAr)3] as initiator has been studied.
Application
Hexyl isocyanate may be employed for the synthesis of following:
- rigid-rod, helical isocyanate-based macromonomers
- rod-coil-rod triblock copolymers with 2-vinylpyridine, by living anionic polymerization
- chiral poly(n-hexyl isocyanate) (PHIC) macromonomers, by living anionic polymerization

The synthesis of rigid-rod, helical isocyanate-based macromonomers was achieved through the polymerization of hexyl isocyanate and 4-phenylbutyl isocyanate, initiated by an exo-norbornene functionalized half-titanocene complex. Sequential ruthenium-mediated ring-opening metathesis polymerization of these macromonomers readily afforded well-defined brush block copolymers, with
