Cross‐linking reactions on polyamides by bis‐ and tris(maleimide)s

Abstract 12 bis‐ and tris(maleimide)s were synthesized and characterized and their reactions with polyamides in the melt were examined. It was found that the double bonds of the maleimides react with terminal amino groups of the polyamides to form elastomeric networks. The chemical and physical properties of these elastomers were examined. Mixtures of bis‐ and tris(maleimide)s with amino‐terminated polyamides can be applied as hot melt adhesives with high tensile and shear strength, with high thermal stability and high chemical resistance.
