Synthesis and Characterization of Sulfonated Polyamides
摘要
Abstract
Two kinds of sulfonated monomers were synthesized, i. e. , 1,4-bis(4-carboxyphenoxy)benzene-2-sulfonate(BCPOBS-Na) and 4,4'-diaminodiphenyl ether-2,2'-disulfonic acid(ODADS). Then non-sulfonated monomer was reacted with sulfonated monemoer, respectively, via the Yamazaki-Higashi phosphorylation method in the presence of triphenylphosphite(TPP) , pyridine( Py) and halide salts to give high molecular sulfonated aromatic polyamides (SPA-1 and SPA-2). The polymers were obtained in quantitative yields with inherent viscosities between 0. 6 and 0. 8 dL/g. The structures and properties of obtained solfonated polyamides were confirmed by FTTR, 1 H NMR and TGA. The results show good solubility in polar solvents, high thermal stability, good film forming ability and excellent mechanical properties.关键词
