Abstract
Thermosetting compositions comprising an N,N'-diphenylene-bis-imide of an unsaturated carboxylic acid and at least one non-imido comonomer copolymerizable therewith, are storage-stabilized against recrystallization of the bis-imide therefrom, by formulating same in the presence of a recrystallization preventing amount of an N,N'-toluene-bis-maleimide. The resultant compositions are useful solventless casting resins; also as coating/impregnating compositions.
