Abstract
The present invention provides amorphous maleimide-bismaleimide hybrid mixtures and methods for synthesizing such mixtures by condensation of diamine compounds with maleic anhydride along with one or more additional anhydrides. The invention provides a route to get passed the high melting point and the solubility issues of bismaleimide resins, yet to still obtain the good thermo-mechanical properties of these valuable molecules.
