【Abstract】 The diazoresin has been prepared by condensation reaction from paraformaldehyde [(CH2O)n] and diphenylamine4diazonium salt[-N+2X-] in concentrated sulfuric acid. The effects of stoichiometric ratio, condensation temperature and reaction time on specific viscosity of the diazoresin were studied. With the molar ratio of (CH2O)n/-N+2X-=12 at condensation temperature of 0￣5 ℃, diazoresin with fair useful property was obtained.更多还原
