A thermohardenable structural adhesive material that upon curing has an elongation at break of at least 10% and has a glass transition temperature (Tg) of 80° C. or higher and is useful as a structural adhesive in automobiles to reduce the deformation of bonds particularly during accidents, the adhesive is dry to the touch at ambient temperature and can be melt processed at temperature below that at which thermohardening occurs. The adhesives are useful in applications requiring a combination of high strain to failure, glass transition temperature more than 80° C., high stiffness and high strength. This combination is of particular interest in the aerospace and automotive industries.
