Beschreibung
Zusammenfassung:Novel N,N,N',N'-tetraacetyl aromatic diamine compounds shown by the general formula (1) (1), wherein R is +tr X is Br or Cl, Y is alkylene group or akylidene group having 1-3 carbon atoms, carbonyl group, sulfonyl group or oxygen atom and m and n is 0 or an integer of 1-4, are produced by reacting 1 mole of aromatic diamine having the general formula H2N-R-NH2 (2) with at least 4 moles of acetic anhydride. These compounds are used as a flame retardant for polyamides.
