Disclosed are halogenated diethyltoluenediamines of formula I, wherein either R1 is an amino group and R2 is chlorine or bromine, or R2 is an amino group and R1 is chlorine or bromine, and isomeric mixtures thereof. The halogenated diethyltoluenediamines of formula I are useful as chain extenders for polyurethanes and hardeners for epoxy resins having a relatively long gel time.
本发明涉及公开式I的卤代二乙基甲苯二胺,其中R1为氨基且R2为氯或溴,或者R2为氨基且R1为氯或溴,以及其异构体混合物。公式I的卤代二乙基甲苯二胺可用作聚氨酯的链延长剂和具有相对较长胶凝时间的环氧树脂的硬化剂。
