چکیده مقاله
A novel sulfone ether amide diamine was prepared through a two step synthetic route At first, 3,3' sulfonyl bis 1,4 phenylene bis oxy dianiline was produced from nucleophilic aromatic substitution reaction of 3 aminophenol with dichlorodiphenyl sulfone in the presence of K2CO3 In the second step, reaction of this compound with isophthaloyl chloride resulted in preparation of a unique aromatic diamine containing amide, ether and sulfone groups Then three different kinds of poly sulfone ether amide imide s were prepared by polycondensation of synthesized diamine with different dianhydrides including pyromellitic dianhydride, benzophenone tetracarboxylic dianhydride, and hexafluoroisopropylidene diphthalic anhydride The structures of synthesized monomers and prepared polymers were characterized using elemental analysis, 1H NMR and FTIR spectroscopy method Thermal behavior and stability, inherent viscosity, and solubility of polymers were studied As the polymers showed high thermal stability and improved solubility, they potentially can be used in high performance applications including aerospace and microelectronics industries
