Abstract

La présente invention concerne une résine d'amine aromatique contenant de la diphénylamine, qui est un sous-produit, en quantité réduite ; une résine de maléimide obtenue à partir de la résine d'amine aromatique ; une composition de résine durcissable produite à l'aide de la résine d'amine aromatique et de la résine de maléimide ; et un article durci obtenu par durcissement de la composition de résine durcissable et qui présente une remarquable résistance à la chaleur, une faible hygroscopicité et de faibles propriétés diélectriques, et qui se révèle ininflammable et résistant. La résine d'amine aromatique selon la présente invention est une résine d'amine aromatique contenant un composé représenté par la formule (1), ledit composé étant produit en faisant réagir de l'aniline avec un dérivé aralkylique de bishalogénométhyle ou avec un dérivé d'alcool aralkylique, la diphénylamine, qui est un sous-produit, étant présente à hauteur de 1 % en poids au maximum. Dans la formule, X représente un groupe hydrocarboné aromatique substitué ou non substitué comportant de 6 à 18 atomes de carbone ; et n représente une valeur moyenne et peut varier de 1 à 10, bornes incluses (c'est-à-dire 1 ≤ n ≤ 10).
