| Abstract: | 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 ( T g).The softening temperature was about 260℃ and there were two decomposition temperatures in the dynamic thermogravimetry. |
