ABSTRACT:
Described herein are novel bismaleimides and prepregable resin compositions comprising these bismaleimides and one or more liquid coreactants and optionally, one or more other additives. The novel bismaleimides, such as alpha, alpha-bis-(4-maleimidophenyl)-meta-diisopropylbenzene, are characterized by the presence of three aromatic rings in the molecular structure and in some respects optimize the desirable characteristics of the one or two and four atomatic ring-containing bismaleimides in resins prepared therefrom.
