Polyaromatic ether sulfoxides were prepared by low temperature solution copolymerization of diphenyl ehter with thionyl chloride in the presence of aluminum chloride 1
2-dichloroethane and N-methylpyrrolidone.The effect of using N-methylpyrrol-idone with aluminum chloride and mole ratio of monomers upon polymerizaton reation was investigated.Properties of polymers were characterised by IR
DSC
TG
X-ray diffraction etc.The results showed that these polymers didn’t crystallize but had a high glass transition temperature (Tg).The softening temperature was about 260℃ and there were two decomposition temperatures in the dynamic thermogravimetry.
