FIELD: chemistry.
SUBSTANCE: invention relates to prepolymers, to compositions containing prepolymers, to methods of producing prepolymers, and to the use of prepolymers in sealants in the aerospace industry. Prepolymer in a backbone contains a ligand capable of binding to a metal.
EFFECT: invention makes it possible to obtain cured sealants having improved tensile strength and improved adhesion to metal surfaces.
