New intrinsic self-healing polymers with outstanding mechanical performance are presented. For this purpose, sterically hindered amines were utilized to crosslink isocyanate containing poly(methacrylates) resulting in urea crosslinked networks. The reversibility of the urea bond during thermal treatment could be utilized to induce self-healing ability and could be proven using various techniques.
