Abstract

The synthesis of a new epoxy resin of oligosalicylaldehyde by the reaction with epichlorohydrin is reported. New resin’s epoxy value and chlorine content were determined and found to be 25% and 1%, respectively. The characterization of the new resin was instrumented by FTIR, 1H NMR, scanning electron microscopy, and thermal gravimetric analyses. TGA results showed that the cured epoxy resin has a good resistance to thermal decomposition. The mass losses of cured epoxy resin were found to be 5%, 10%, 50% at 175Β°C, 240Β°C, and 400Β°C, respectively. On the curing procedure the resin was cured with polyethylenepolyamine at 25 Β°C for 8 h and 100Β°C for 1.5 h. The FTIR spectrum of new epoxy resin gave the peak of oxirane ring at αΉ½ = 918 cmβˆ’1.
