Abstract

Epoxy resins are the most commercially important polymers, which have found a broad range of applications because of their excellent adhesion, toughness, insulation and good physical and chemical properties. In this project, liquid epoxy resin with narrow molecular weight distribution was synthesized by polymerization reaction of epichlorohydrin and bisphenol A in molar ratio of 12 to 1 in presence of sodium hydroxide. This product was characterized by FTIR and 1H NMR spectroscopy and its thermal degradation was studied by using DSC and TGA thermograms. Epoxy equivalent and chlorine content were determined by chemical analysis. Some effective parameters such as the method employed and the adding amount of sodium hydroxide in the reaction system were changed in order to gain qualified epoxy resin. Epoxy equivalent of this resin was 0.53 per 100 g of resin and its chlorine content was 0.25 percent. Epoxy equivalent weight of this resin was 169 g per one equivalent of resin. Viscosity of the product was studied at different temperatures and the constituting liquid epoxy resin was determined by TLC.
