Abstract

Four azo-phenol-formaldehyde resins were synthesized via reaction of phenol with four different types of diazanium salts then resulted azo dyes reacted with formaldehyde. Structures of all new compounds were elucidated with Fourier transform infrared spectroscopy, Nuclear magnetic resonance and Differential scanning calorimetry to assess the thermal characteristics of the produced resins (DSC).
