FIELD: chemistry.
SUBSTANCE: invention relates to a urethane-containing prepolymer with terminal groups which are Michael acceptors, as well as to a sealing composition, a cured sealant and an aerospace device. Said urethane-containing prepolymer with terminal groups which are Michael acceptors includes a reaction product of (a) a urethane-containing adduct with terminal isocyanate groups and (b) bis(vinylsulphonyl)alkanol. Said urethane-containing isocyanate-terminated adduct includes a reaction product of (i) a sulphur-containing adduct with terminal hydroxyl groups and (ii) diisocyanate.
EFFECT: use of said urethane-containing prepolymers improves properties of the sealing compositions, particularly high tensile strength.
