SYNTHESIS AND CHARACTERIZATION OF DIPHENYLAMINE DIAZONIUM SALTS AND DIAZORESINS

3-Methoxydiphenylamine-4-diazonium salts (MDP-4-DS), 2-sulfodiphenylam ine-4-diazonium salts (SDP-4-DS), N-methyldiphenylamine-4-diazonium sa lts (NMDP-4-DS), N-methyldiphenylamine-2-diazonium salts (NMDP-2-DS), carbazole-3-diazonium salts (C-3-DS), N-ethylcarbazole-3-diazonium sal ts (NEC-3-DS) tall of them with various counterions) and the correspon ding diazoresins were synthesized. The photochemical and thermal decom position properties of the salts and resins were studied. The results show that among the diazonium salts and resins studied, the MDP-4-DS a nd its resin exhibit the highest thermostability as well as high photo sensitivity. The influence of the counterion on the properties of the diazonium salt and the diazoresin was also investigated.
