Thermal degradation of hexafluoropropylene-tetrafluoroethylene copolymer (I) at 350-900?was studied by pyrolysis-gas chromatog. combined with IR and TGA. From the relative content of C3F6 or C2F4 plotted against the pyrolysis temperature, the copolymer clearly decomposed in 2 stages. The mechanism of thermal degradation of I was discussed.
