ABSTRACT:
A novel aliphatic diisocyanate, namely 1,4-bis(2-isocyanatoethyl)cyclohexane, is disclosed. Polyurethanes derived from this diisocyanate exhibit advantageous properties. Illustratively, polyurethane elastomers prepared from the above diisocyanate, a polymeric diol and a low molecular weight diol extender, possess significantly improved resilience properties and are useful in the preparation of automobile bumpers, fenders and the like.
