Description	Průběh a vlastnosti reakčních produktů oxidace 4-aminodifenylaminu s peroxydvojsíranem amonným v kyselém vodném roztoku etanolu byly porovnány s reakcí 2-aminodifenylaminu. Polovodivé oligomery 4-aminodiphenylaminu a nevodivé oligomery 2-aminodifenylaminu s váhovým průměrem molekulové váhy 3700 a 1900 byly připraveny užitím molárního poměru oxidantu a monomeru 1.25. FTIR a Ramanova spektroskopie potvrdily, že v případě 4-aminodifenylaminu převažuje tvorba lineárních Nprim-C10 vázaných oligomerů, zatímco předpokládají síťování a tvorbu fenazinových strukturních jednotek v oligomerech v případě 2-aminodiphenylaminu. (cs) The course of oxidation of 4-aminodiphenylamine with ammonium peroxydisulfate in an acidic aqueous ethanol solution as well as the properties of the oxidation products were compared with those of 2-aminodiphenylamine. Semiconducting oligomers of 4-aminodiphenylamine and nonconducting oligomers of 2-aminodiphenylamine of weight-average molecular weights 3700 and 1900, respectively, were prepared by using an oxidant to monomer molar ratio of 1.25. FTIR and Raman spectroscopic studies confirm the prevalent formation of linear Nprim-C10 coupled oligomers of 4-aminodiphenylamine and suggest branching and formation of phenazine structural units in the oligomers of 2-aminodiphenylamine.
