ABSTRACT:
This invention relates to thermosettable bismaleimide resin compositions, and to cured bismaleimide thermoset resins.
The compositions of the present invention contain an additive which is the reaction product of (i) an epoxide, and (ii) a second reactant selected from an aromatic polyhydroxyl, an aromatic amide or an aromatic amine. The thermoset resins having surprising strength and modulus properties, and are suitable for use in the preparation of composite materials.
