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.
