摘要： A method for producing a modified form of an aromatic amine compound represented by the following structure I: where A is an amine group— NHR, R is independently selected from hydrogen, linear and branched alkyl groups having 1 to 6 carbon atoms, preferably A is NH 2 ; X is a halogen selected from CI, Br, F, I, and At, or hydrogen (H). The method includes heating the aromatic amine compound, in its initial crystalline form, to a temperature above its melting point in order to obtain a molten material, then cooling the molten material to a temperature below the melting point of the crystalline compound so as to produce an amorphous, glassy form of the aromatic amine compound. The modified aromatic amine compound is suitable as a curing agent in resin compositions that are used for fabricating fiber-reinforced composites.

摘要： A curing agent composition contains at least one multifunctional aromatic amine that forms a crystalline solid at 25°C, and at least one halo-substituted diethyltoluenediamine, in an amount effective to inhibit crystallization of the at least one multifunctional aromatic amine. A curable resin composition contains at least one epoxy compound having at least two epoxide groups per molecule of the epoxy compound and the curing agent composition. Methods for inhibiting phase separation of a curing agent composition or curable resin composition that contains at least one multifunctional aromatic amine that forms a crystalline solid at 25°C include a step of adding to the respective composition at least one halo-substituted diethyltoluenediamine in an amount effective to inhibit crystallization of the at least one multifunctional aromatic amine. The compositions and methods are useful in making fiber reinforced resin matrix composite articles.
