摘要: Structurally different poly(arylene ether sulphone) (PES) copolymers were synthesized by reacting stoichiometric amount of dichlorodiphenyl sulphone (DCDPS) with bisphenols. The molar ratio bisphenol-A and phenolphthalein (ESP)/hydroquinone (ESH)/resorcinol (ESR) was varied to prepare nine copolymer samples. Structural characterization done FT-IR 1H-NMR studies. initial decomposition temperature as well maximum rate mass loss in ESR ESH similar a marginal decrease these temperatures observed increasing the isopropylidine units backbone. High char residue at 800°C polymers having high content phthalein units.
