A composition that toughens and impact modifies epoxy resin based compositions comprising one or more co-polyamides and one or more block copolymers with polyamide and polyether blocks. The disclosure also relates to epoxy resin compositions containing the composition comprising one or more co-polyamides and one or more block copolymers with polyamide and polyether blocks and films, adhesives, foamable compositions and foamed compositions containing such a composition.

Epoxy composition containing copolyamide and block copolymer with polyamide and polyether blocks

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&#xb0; 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&#xb0; C., high stiffness and high strength. This combination is of particular interest in the aerospace and automotive industries.
