Triazene compounds as a novel and effective class of flame retardants for polypropylene

Four triazene derivatives have been synthesized, i.e. bis-4,4′-(3,3′-dimethyltriazene)-diphenyl ether (1), bis-4,4′-(3,3′-diethyltriazene)-diphenyl ether (2), 2,2,6,6,-tetramethyl-1-phenylazo-piperidine (3) and 4-hydroxy-2,2,6,6-tetramethyl-1-phenylazopiperidine (4). Their thermal properties were de...
