Abstract
In this work, a triblock copolymer polytetrahydrofuran–block-poly(glycidyl azide)–block-polytetrahydrofuran was synthesized through ring-opening polymerization of epichlorohydrin and tetrahydrofuran catalyzed by BF3-diethyl ether at 30°C, and further modification. The structure of the polymer was verified by IR, 1H and 13C NMR spectroscopy. The decomposition and kinetic parameters of the block copolymer such as its activation energy and frequency factor were determined using the differential scanning calorimetry and thermo-gravimetric analysis. The results revealed that the main thermal degradation for the copolymer occurs in the temperature range of 220–250°C. Finally, the effect of polytetrahydrofuran content on the thermal stability and decomposition temperature of the overall copolymer was investigated.
