Abstract:
An object of the present invention is to provide a bismaleimide using an aliphatic diamine, in which acid components remaining as an impurity at a very small amount in the bismaleimide have been effectively removed, that is, a bismaleimide using an aliphatic diamine, an acid value of which has sufficiently been reduced, and a method for producing it. There are provided a bismaleimide using an aliphatic diamine as a diamine component, characterized in that an acid value thereof is 2 mg-KOH/g or less, and a method for producing the bismaleimide, comprising adding carbodiimide to a solution comprising a crude bismaleimide having an acid value of more than 2 mg-KOH/g, and reacting acid components in the crude bismaleimide with carbodiimide.

Claim (Index 3):
A method for producing the bismaleimide as defined in  claim 1 , comprising:\n adding a carbodiimide to a solution comprising a crude bismaleimide having an acid value of more than 2 mg-KOH/g; reacting acid components in the crude bismaleimide with the carbodiimide; and thereafter, removing a urea derivative of the carbodiimide.
