(Cyclo)alkylenediammonium compounds corresponding to the formula: <IMAGE> wherein X is halogen, R is an alkylene or cycloalkylene group containing 2-15 carbon atoms, each R' alone is an alkyl, cycloalkyl, or aralkyl group, and R'---R' together represent an alkylene, cycloalkylene, or aralkylene group are prepared by esterifying a tetrahalophthalic anhydride with a mono- or dihydroxyalkane, -cycloalkane, or -aralkane having a boiling point below 250 DEG C. to form a half-ester and then reacting the half-ester with a stoichiometric amount of a diaminoalkane or diaminocycloalkane containing 2-15 carbon atoms.
