Abstract
Benzofuro[2,3-b]benzofuren-2,9-dicarboxylic acid reacts with a number of diaryl ethers in phosphorous pentoxideimethanesulphonic acid (PPMA) media. The resulting poly(ether-ketone)s and poly(ether-ketone-sulphone)s, obtained by direct polycondensation reaction, are characterized with FT-IR spectroscopy and elemental analysis . Thermal properties of polymers are investigated by TGA and DSC methods and their heat stabilities are compared. The thermal properties can be modified by introducing an equimolar amount of a diacid or diarylether by which thermal cross-linking sites are provided.
