摘要: Abstract The thermal degradation of anionically modified poly(ethylene terephthalate) (PETSTA/K) has been studied over the temperature range 293–773 K in nitrogen and air. Dynamic thermogravimetry, differential analysis i.r. spectroscopy were used. It stated that incorporation metal sulphonate groups into matrix affects stability copolyester, especially at above 693 K. onset decomposition decreases with increasing content ionic co-units polymer chains. PETSTA/K is less air than an inert atmosphere mechanism more complex.
