Abstract:

Dipropargyl ether of bisphenol A was synthesized by using phase transfer catalyst and was characterized by FT-IR，1H NMR and ¹³C NMR.A polymer of dipropargyl ether of bisphenol A was prepared.TG and DTG were used to study the thermal degradation kinetics of the polymer in N₂.The kinetic parameters were calculated by methods of Kissinger and Ozawa.The results showed that the apparent degradation reaction order of the polymer of dipropargyl ether of bisphenol A was 1 in N₂ via the Coats-Redfern method.Thermal degradation activation energies of the polymer were 166.36 kJ·mol^-1 and 199.90 kJ·mol^-1 by methods of Kissinger and Ozawa respectively.The temperature of 60 s lifetime was 461℃ in N₂.
