Abstract
An elastomer obtained by reacting at a specific ratio an isocyanate-terminated prepolymer formed by reacting at a specific ratio of polymer containing a diene polymer having a terminal hydroxyl group with a diisocyanate compound, with a curing agent having a terminal hydroxyl or amine group, is especially excellent as a tire filling material. A tire prepared by filling this elastomer is valuable as an elastic tire of a public vehicle.
