Degradation behaviours various chain scissions

Numerous ways to evaluate the degradation behaviour of polyarylene sulfones are reported in the literature. Danilina and co-workers [17] used infrared (IR) analysis for the pyrolysates of PES and PSF along with a change in the absorption peaks after two hours at 470 °C, they showed the formation of sulfur dioxide and phenol from the scission of sulfone and ether linkages. Crossland and co-workers [18] reported the results of TGA and Py-MS in the evaluation of the pyrolysis mechanism and pyrolysates of various PSF main-chain scission and hydrogen abstraction were indicated. However, the relative stability of the different PSF could not be postulated... [Pg.166]
